Stargate SG-1

1Children of the Gods

An alien similar to Ra appears out of the Stargate, killing five soldiers and kidnapping another, a year after the original Stargate mission. A new team is assembled, including some old members, and they go in search of the missing soldier in order to find out how Ra could still be alive. Meanwhile, the alien Gou'ald kidnap Sha're and Skaara, implanting them with symbiotes and making them Gou'ald hosts.

2The Enemy Within

Upon returning to the SGC from there first mission, SG-1 learns that Major Kawalsky, O'Neill's right-hand man, has become infected by a Goa'uld during their mission. As the SGC's doctors look for a way to remove the Goa'uld, Colonel Kennedy interrogates Teal's, who O'Neill wants to join SG-1. As time goes on and Kawalksy's mind is taken over more and more by the Goa'uld, doctors preform emergency surgery in a desperate attempt to save Kawlasky. But they prove to be too late as Kawlasky escapes and activates the base's self-destruct, leaving only Teal'c to stop him.

3Emancipation

SG-1 arrives on a planet controlled by the Shavadai, decedents of Mongols, who view women as subservient and submissive. The presence of SG-1 Captain Samantha Carter causes an instant uproar. Carter is forced to adapt to the custom's, but is soon kidnapped by the chief's son who trades her in another village. As SG-1 tries to find her, Carter must survive in this society to bring about freedom for all women.

4The Broca Divide

SG-1 visits a nameless planet which fascinates Daniel as a casus of the "Broca divide", the cohabitation of stone - and bronze age people: the Touched, aggressive cavemen, and a Minoian urban civilization, the Untouched, but with a twist: it's one population, a disease can turn anyone of the Untouched, who is then banished for life, to prevent contagion, even the king's daughter. Dr. Jackson's frustration when Jack decides to return, because no goa'uld threat is found, won't be repeated as the President has added scientific research to the prioritary objectives, but in this case they didn't leave fast enough: very soon members of the team get symptoms of reversal to an animal state, infecting others on the base. General Hammond is forced to have the whole mountain quarantined. As both Teal'c and Daniel and found to be immune, they return to get a blood sample from the Untouched, while Dr. Fraiser searches frantically for an explanation and cure...

5The First Commandment

SG-9's anthropologist Frakes is captured during a mission on a planet of cave-dwellers, where direct sunlight is unbearable, and killed by their own Captain Jonas Hansen, who became a murderous tyrant after being treated like a god by the primitive inhabitants, drunk with power, and has them build a temple in his honor well beyond their primitive means and manpower. His escaped team mate Lieutenant Connor refuses to return with SG-1, which soon finds him captured and tied up in the sun with other non-collaborating team survivors. Captain Samantha Carter allows herself to be captured trying to free them, so she can talk to Hanson, an ex of hers, who claims the temple should save the people when he as 'their god' installs an old goa'uld device he expects her to repair. When Teal'c hears about it from local escapee Jamala, he warns hat technology can only create a field between two devices, so SG-1 must find a second one, then overpower the false god...

6Cold Lazarus

When Jack is injured unintentionally by a crystal alien, the alien duplicates Jack's form and out of fear of retribution tries to heal Jack. He returns to Earth in place of Jack, while Jack is still unconscious on the planet, to find the one thing he feels will accomplish this; the one thing that cannot be found again. Meanwhile, the 'real' Jack has returned and is trying to convince SGC that he is who he says he is.

7The Nox

With the Stargate program in danger of being terminated, the team is under pressure to find technology. Visiting a planet where they believe there is a creature that possesses the secret of invisibility, they encounter Apophis and his guards. Both sides receiving mortal wounds, they are aided by the planet's inhabitants, the Nox, a gentle people with a very large secret.

8Brief Candle

On planet Argos SG-1 arrives at a stargate inside the Mycenean temple of the mythical founding hero Pelops, whose return is awaited. There Daniel delivers the baby of a Chosen couple. After eating a piece of the special cake at the celebration, Jack wakes up, having laid with Kynthia. At sunset all natives fall into a deep sleep. Teal'c and Daniel discover a temple archive in linear A, a Minoan era script which is an archaic goa'uld dialect. The team finds the life cycle on Argos is incredibly fastened: factor 250, as a genetic experiment set up by Pelops. It must be somehow contagious, as Jack also starts to age terrifyingly fast. Dr. Fraser and Sam find it's something in the blood, but not a virus: replicators, and Jack has more of them: he's aging even faster, to die in about two weeks. Finally Jack investigates the importance of Pelops' first law that nobody may leave the village and it's link with a goa'uld device found when his statue breaks...

9Thor's Hammer

SG-1 goes to the planet Cimmeria in search of allies against the Goa'uld. Upon arrival, Jack and Teal'c are trapped in a labyrinth, where the only exit is through Thor's Hammer, a device to destroy Goa'uld, but preserve the host. Daniel Jackson must destroy the device that could someday have saved his wife in order to free his friends.

10The Torment of Tantalus

Daniel Jackson discovers that the Stargate was activated in 1945 and a young professor went through, never to return. Together with his still living fianc?e, the SG1 team discover the now aged professor, naked and trapped in a decaying fortress, containing the secrets of an Ancient alliance. Will they be able to rescue him and escape to earth in time?

11Bloodlines

An experimental drug to replace Teal'c's goa'uld as immune system fails, only gives him nightmares about the traumatic implantation in his body, prim'ta which turns a Jaffa child into a goa'uld drone, and its impending for his son Ry'ac, whom he never told the USAF about. Now he tells Jack and proposes a mission to get symbionts on his home planet Chulac, where they are plenty, but their last visit made them many enemies and hopefully just one friend. Once informed, the general prefers a team mission in disguise to virtual suicide by Teal'c. They pretend to be a legation from Apophis, hide their disguise and find Teal'c's home burnt down as part of his disgrace as shol'va (traitor) but meet Jaffa master Brae'tac, his mentor, who expected him to return to his family for Ry'ac's prim'ta and shows him and Jack where they live as kresh'ta (outcasts) in a slum, just in turn to prevent the ceremony, to his wife Drey'auc's fury, who told Ry'ac to be an orphan; Jack sees the boy's sickness is scarlet fever, but can't guarantee full healing even on earth, in the meantime Teal'c implants his own symbiont. Meanwhile Daniel and Sam traced a real party of Apophis priests who deliver symbionts to a temple dependency, which they rob of a sample; Daniel destroys the rest, against Sam's ethics. Although it's not quite mature, Brae'tac uses it to save Teal'c, who must return to earth if possible...

12Fire and Water

O'Neill, Carter and Teal'c return through the Stargate shell-shocked and distressed to announce that Daniel Jackson was killed. But Jackson was captured by the last survivor of an aquatic race, who planted false memories in the other members of SG1. Can the team remember and return to rescue Daniel?

13Hathor

The Goa'uld Hathor (one of the mothers of all Goa'uld), brainwashes the men of the SGC with pheromones, and nearly makes Jack a host to a larva conceived with Daniel. She flees after the unaffected women of Stargate Command retake the facility.

14Singularity

SG-1 rescues a small girl who turns out to have had an inoperable Naquadah bomb put in her by Nirrti to destroy the SGC. Ultimately the girl is given to the care of Janet Fraiser, the SGC medic, after they discover that the bomb will dissolve if she is kept away from the Stargate.

15Cor-Ai

SG1 travel to a planet where Teal'c is recognised as once having been head Jaffa to Apophis. He is arrested for the murder of a villager and put on trial for his life. Then other Jaffa attack the village. Will SG1 be able to save Teal'c and prove that he has changed allegiance?

16Enigma

On their first visit to a new planet, SG-1 finds it subject to totally destructive volcanic activity and saves ten natives, the Tollan, a far more technologically advanced society. Their leader Omoc isn't grateful, nor interested in such a primitive race as the earthlings or any of the 'even more primitive' planets which are prepared to host them. Only one Tollan, Narim, shows an active interest in life on earth, especially in captain Samantha Carter and the cat Schrodinger she gives him, explaining his planet was destroyed after the Tolan supplied an unlimited energy source to a primitive neighboring planet which abused it for a cataclysmic weapon. Meanwhile the White House authorized NID colonel Mayborn to take charge over the Tollan for military purposes, exactly Omoc's nightmare...

17Solitudes

When SG-1 arrives on a mission to the Tollan planet, goa'uld troops are waiting to fire at them; only Teal'c and Dr. Daniel Jackson, who gets hurt, escape back to earth, and the stargate is damaged, temporarily out of order. Captain Carter realizes she and colonel O'Neill, who has a broken leg and rib, must be on the wrong planet, probably a mis-dialed address or stargate malfunction: they are stuck next to a Stargate in a cave on an icy wasteland. Her attempts to get the stargate working properly are all frustrated as she can't figure out what's wrong with it, just as Daniel's efforts to guess where they can be, till he has a radical, yet simple idea ... .

18Tin Man

When SG-1 lands on Altair, they are automatically processed by the incredibly advanced machinery of the sole surviving native, Harlan, who insists they are 'better' and can never go back. They return, only to be incarcerated when it becomes clear they are not themselves but cyborg copies. Once their energy runs out, they must return, but once again Harlan insists they can't ever leave. He needs needs help to keep the underground biosphere running under a planet totally non-viable above ground.

19There But for the Grace of God

While exploring an alien stargate complex on P3R-233, Daniel Jackson finds an alien artifact that appears to be a mirror and touches it, receiving a mild jolt. No thinking anything of it, Daniel goes to find the rest of SG-1 who appear to have left him behind. Traveling to Earth, Daniel finds himself in an alternate reality where O'Neill is the general in charge, Carter is a civilian scientist, Catherine Langford is the civilian head of the program, and where he never joined the program. What's worse is that the Goa'uld are invading Earth, killing 1.5 billion people. With Teal'c leading the Jaffa assault on Stargate Command, Daniel must escape through the stargate with information that might save his world from such grim fate or convince his counterparts in this alternate reality to help prevent a similar apocalypse in his own reality.

20Politics

Daniel Jackson was eager to warn earth about the probable massive goa'uld attack threat, but finds Starbase is under a more down-to-earth threat: Senator Kinsey, the ambitious chairman of the Senate Committee which must approve the program's annual $5.7 billion budget, was not impressed when the President disclosed its extraterrestrial mission reports. Arriving for a visit, Kinsey tells the team he's most unlikely to be persuaded, and indeed while SG-1 points out its merits and dangers from events on various planets, Kinsey and his military aid, USAF Lt. Colonel Bert Samuels, question or belittle both systematically and focus on costs and risks they contend outweigh the benefits, even when Daniel's theory is presented...

21Within the Serpent's Grasp

General Hammond has tried everything to get the senates decision to shut down his space program undone, but the president personally refuses to 'commit political suicide': the Stargate will be buried. Daniel's insistence the danger for earth as a whole outweighs everything convinces his military SG-1 colleagues to ignore the commander general's command and dial the address the goa'ald invasion started from in the parallel dimension he visited. They arrive not on a planet but a new, superior type of starship, already launched by hyper-drive. A 'video' proves it belongs to Apophis, who gives command aboard to his son Klorel, whose host is no other then the team's young Abydos friend Skaara, yet overpowering him seems their best move, while Sam installs explosives in the death glider deck with a 24 hours timer just in case, but Jaffa manage to liberate Klorel and the ship goes far faster then expected...

1The Serpent's Lair

As the ship carrying Klorel and SG-1 arrives in Earth orbit, the team is captured and held prisoner. Meanwhile, the SGC has been alerted to the presence of the ship and another carrying the Goa'uld Apophis. As Lt. Colonel Bert Samuels attempts to convince Hammond that his plan of launching nuclear missiles against the ships will work, SG-1 is freed by Jaffa rebel Bra'tac. After Samuels plan fails, SG-1 and Bra'tac race to come up with a plan to destroy both ships and stop the invasion.

2In the Line of Duty

During a visit to the Nasyan planet, under the first goa'uld attack in centuries, a victim's breath given mouth-to-mouth infects Sam, at first unnoticed. Soon her behavior changes, more military and assertive, and she seems to suffer from amnesia. Cassie senses immediately Sam really hosts a goa'uld, which is confirmed by her attempt at gunpoint to escape via the star-gate, and since the aliens now seem able to enter via small skin wounds as in her throat, Dr. Fraser points out there may be others in the base. Sam is jailed but allegedly hosts Jolinar, a 'Tok'ra' or good, anti-warlord goa'uld underground rebel, being chased by an 'ashrak', a goa'uld hit man, who has already started his deadly assignment on earth...

3Prisoners

SG1 inadvertently help a desperate criminal and is charged and sentenced as accessories to his crime. They are banished to a desolate, brutal penal colony and strike a deal with a powerful female prisoner to help them escape. But is this prisoner hiding something from them?

4The Gamekeeper

Exploring a strange and beautiful garden, SG1 comes across a dome containing a race that are connected to machines. The team are captured by the machines and rendered unconscious, but awake to find themselves reliving pivotal moments of their lives, over and over again. Then they discover it is virtual reality and a mysterious keeper appears to persuade them to try different outcomes for the moments. But can the team escape his clutches, when they don't know what is real and what is not?

5Need

Whilst walking through a forest on a planet, Jackson saves the life of a beautiful princess who is about to kill herself. SG1 is taken prisoner, but Daniel is freed by the ruler when he finds out that he saved his daughter. The rest of SG1 is sent to work in the mines for the rest of their lives. Jackson falls in love with the princess, but also becomes intoxicated by frequent use of a Sarcophagus. Will he come to his senses before the rest of SG1 are worked to death?

6Thor's Chariot

O'Neill and the team return to Cimmeria, the planet where they destroyed Thor's Hammer to help Teal'c escape. They find that the Goa'uld have invaded and many of the people are dead. Can they help to find Thor's weapons to fight off the invasion before they are all captured or killed?

7Message in a Bottle

On a mission SG-1 finds an ancient, apparently lifeless metallic sphere-shaped object and brings it home to study the minute, elaborate writing on it, hoping they can then open it. Jack was eager to get away from the tedious examination, which seemed to be going nowhere, on yet another planetary mission, when the sphere suddenly 'warms up' and surprises everyone by sprouting long spikes in various directions, one of which happens to go straight trough Jack's body which soon infects. A staff-weapon doesn't even affect it, Sam fears it is only being fed energy. The fast-spreading infectious organism causes necrosis even on dead material, such as Jack's uniform and, worse, the computer system; yet it is slowed down by an antibiotic, tetracycline; UV-light shows it even got trough the walls, sneakily infecting everyone, starting with young control chamber Lieutenant Graham Simmons, who is allergic to the tetracycline (and clearly has a timid crush on Carter), only Teal'c is protected by his symbiont. When a blow-torch is about to sever the spike trough Jack, the sphere suddenly sprouts length shifting trough him. Carter suggests limiting the oxygen supply which the organism needs, but auto-destruct kicks in with a 3 hours count-down, and can no longer be overrode because of the damage to the computers. Then Daniel notices a symbol in the gibberish it causes on the computer screens, and believes the sphere is trying to communicate: is it really an aggressor? Sam agrees to try making contact by stopping Jack's medication, he agrees. Indeed this rapidly turns him into the conscious medium of an ancient, otherwise dormant race, which is eager to spread and consume earth, but is now offered an alternative planet to consider...

8Family

Master Bra'tac makes a surprise visit to star-base and tells that Apophis and Klorel managed to escape just before their starship exploded and has Rya'c, Tealc's son, in his power. To maintain his position as system-lord he must restore order on Chulac, so SG-1 goes there, also to look for 'sholva' (outcast) Teal'c's family. They find his wife Drey'auc has remarried with high-ranking Jaffa Fro'tak. Teal'c vows to shun her forever after Rya'c's salvation from Apophis's palace, but the boy refuses to come with his 'hataka' (traitor) father and calls the guards so they must retreat without him and soon see him in Apophis' propaganda, however a deliberate wrong detail suggests he has not completely changed sides yet. A search of Fro'tac's house doesn't find the team; Jack follows their host to the palace and prevents him betraying them. Now Jack mistrusts the return of Rya'c too, Teal'c refuses to doubt his son; the others hesitate, and after their return on earth with the boy...

9Secrets

Whilst O'Neill and Carter head to Washington to be decorated by the President and find a security leak, Jackson and Teal'c go to Abydos (after they unbury their stargate) to see Sha're's father. They arrive to tell him that they have been unsuccessful in finding Sha're, only to discover that she is already on Abydos. But they find that she is pregnant by Apophis and the baby holds the secrets of the Goa'uld.

10Bane

Whilst off-world, the team is attacked by giant insects, one of which stings Teal'c on the back. The bug has actually implanted a virus that converts Teal'c into a living incubator for hundreds of more insects and Teal'c is being eaten alive. The only way to save him is to capture another venomous bug and create an antidote, but time is running out.

11The Tok'ra: Part 1

Carter dreams about herself as Jolinar, the rebel Goa'uld who briefly inhabited her body. With SG-1, she travels to a world to meet the other Tok'ra and form an alliance against the Goa'uld. Meanwhile on Earth, Carter's father, Jacob, with terminal cancer, calls General Hammond to his bedside.

12The Tok'ra: Part 2

The Tok'Ra still need a host for one of their dying leaders; when SG-1 refuse, the Tok'Ra refuse an alliance. Sam is told the blending of symbiont and host can cure cancer. So Sam returns to Earth to tell her father about her real job and offer him the cure if he will be host to a Tok'Ra.

13Spirits

SG-11 does not return from a mission to collect trinium ore. When SG-1 travels to the planet, the mystical Indians there say that the Spirits have captured SG-11. After talking to animals said to incarnate the Spirits, SG-11 is released. Soon after SG teams return to Earth with Indian leader Tonan? to seek a mining agreement and many people disappear at the SGC.

14Touchstone

A climate control device is stolen from a planet and SG1 is accused of the theft. They have to find it and restore it before the planet freezes. Then weather on Earth starts to unexpectedly change and the team believe that the device has been stolen by rogue NID agents. Will they find it in time and how did the NID travel off world?

15The Fifth Race

SG1 travels to a Stargate where O'Neill looks into a strange device that downloads information into his brain. Back on Earth, he starts to speak using a strange language. Carter and Teal'c try to find a solution and become trapped on a burning hot planet, when the Stargate fails to dial out. O'Neill solves the problem by designing a solution, but then he designs a device. But for what purpose?

16A Matter of Time

SG10 are on a planet when one of the binary stars becomes a black hole. They try to escape by dialing Earth, but fail to get back. The SGC sends a probe and sees the black hole, but then they find they cannot disengage the wormhole and the gravitational effects are starting to effect Earth.

17Holiday

The next planet visited by SG-1 holds an unusual surprise: the only person by its star-gate is an old, sick man, known to Teal'c as Machello, since decades a famous adversary of the goa'uld, who even developed his own technology to fight them, was captured and tortured but escaped. He joins them to earth, but Daniel, who touched his recording device, wakes up in the dying body of Machello, which is only discovered after the alien walked of, given a clean bill of health by Dr. Fraiser, in Daniel's body, determined to enjoy life as an earthling, teaming up with homeless Fred, which soon turns bad... While Machello is searched, the others travel back to retrieve the device, but in the process Jack and Teal'c get body-switched too, and Sam fails to figure out on her own how to reverse it...

18Serpent's Song

Following on a Tok'ra tip, SG- goes to a planet where they find the hated Apophis, nearly dying and under attack by death-gliders. They get back with him, realizing he was tortured by a rival system-lord, with lasting harm. Apophis demands sanctuary, provided Dr. Fraiser can save his life, at least on account of the human host, but without a sarcophagus the prognosis for his symbiont is lousy; he offers all his Goa'uld knowledge in exchange for a new host, i.e. his life, revealing he was defeated by the terrible Sokar, once supreme system lord till an alliance lead by Ra and Apophis unseated him. The confrontation with Daniel, on account on Amaunet/Sha're and their son Klorel, and with former prime Teal'c, is bitter for all three. The Tok'ra send Martouf, to warn the Taurai must hand over Apophis, but their warning is ignored- until Sokar proves he can bombard the iris with accelerated particles and ultimately cut trough it, so the White House orders his extradition, but before they can he dies, unlike his host, an Ancient Egyptian temple scribe of Amun...

19One False Step

A UAV glider crashes on PJ2-445 against what looks like a giant mushroom; before the camera gives out, a humanoid is seen. SG-1 is sent to retrieve the flight recorder and finds lots of young mushrooms among the dwellings of the humanoids, naked except for white paint, who seem naively friendly but don't speak, so Daniel has to try scribbling or sign language. When several natives faint, the others chant, apparently in vain, and the team calls medical help, fearing to have initiated an epidemic. Even taking one native to the base, Dr. Frazier fails to find their functioning or cure. Fearing to be infected, Jack and Daniel return too; Teal'c has only a short attack, while minding the strange plant as Daniel asked, and precisely it's symbiosis proves crucial...

20Show and Tell

When an incoming wormhole is established at the SGC, the iris is over-ridden and opened. A young boy appears and tells the SGC that they are in terrible danger from a group of terrorists. But these terrorists are invisible creatures and they are determined to wipe out all humans to prevent them being used as hosts to the Goa'uld.

211969

Trough a flaw in star-gate travel, SG-1 lands back in Cheyenne mountain in 1969, only Teal'c staff weapon prevents them from being incinerated by a Titan rocket launch. They are captured by their own USAir Force, and Carter realizes they can't do or say anything for fear of irreparably altering their own past and thus creating an alternative reality. Yet someone at the base finds on the team an anonymous note to help them- it's Lieutenant George S. Hammond, their future general, who wrote it to his past self and succeeds in allowing them to escape and recuperate their belongings during prisoner transport, so they can search a star-gate to return. The only other help the note offers them are two consecutive dates and exact times. Daniel decides their best chance is meeting Catherine Langford, in New York, without telling the truth or getting caught on the way. While they get a ride from gullible hippies, posing as anti-establishment aliens, Carter realizes the nature of the times: otherwise impossible to predict sun flares...

22Out of Mind

When Colonel O'Neill wakes up, he is told by new staff everything in the star-base is different because he was just revived after 79 years of cryogenic hibernation, as sole survivor of a disastrous SG-1 mission on a goa'uld-ruled planet. He accepts to undergo a 'high tech hypnosis' to retrieve information of use in the present war against them which is going badly, involving earth's ten endangered colonies on other planets. However Major General Trofsky, the new base commander, and his female assistant tell Daniel and Sam, in different sections, that each of them is the sole survivor: it's all make-believe to probe their brains about the weaknesses of earth and the Alliance of the four races. Meanwhile Teal'c awakes on earth, where it took Dr. Frasier months to save him from death, there was no trace of his teammates and he resigns when general Hammond refuses permission to keep searching. O'Neill hears goa'uld language, gets himself free and discovers to be on a fake star-base, frees Sam and Daniel, only to be stopped by the female Goa'uld system-lord Hathor, who employs both Horus and Serpent Jaffa and demands the humans' help against her rival system-lords...

1Into the Fire

2Seth

Stargate is visited by general Jacob Carter on a mission -actually requested by his symbiont Selmak, who wants him to deal with his long-repressed break-up with Sam's brother Mark- to ask SG-1's help in the hunt for the sole system-lord the Tok'Ra never tracked down, Seth, the Egyptian god of chaos and total evil, who plausibly never left earth but hides as Ra put a high price on his head. Daniel finds a plausible series of Seth-cults, each ending in a blood-bad for followers, the latest being outside Seattle, led by Seth Fargo. Jacob and SG-1 arrange to take over the case jurisdiction from the ATF by presidential intervention. As Daniel predicts, they find escape tunnels and get in, but are awaited and disarmed, to be exposed to nish'ta, a powerful biological submission drug, and when Seth senses Jolinar's traces destined for elimination...

3Fair Game

Just when Jack was to speech, in the Secretary of Defense's presence, for Sam's promotion to major, he is suddenly beamed up directly into the space-ship in undetectable earth-orbit of Asgard Thor, who warns him the Goa'uld system-lords have decided after Hathor's defeat to launch an attack on earth hundredfold Apophis's and offers Asgard help to propose alternatively Earth's inclusion in the Protected Planets Treaty, then returns Jack. Thor instructs Jack alone to represent the entire planet, on star-base, against a System-lords delegation of three: the Ancient first supreme Greek god Cronos, who once toppled Sokar, Yu the Great or Yu-huang Shang Ti, the first Chinese dragon Emperor, and Nirrti, the Hindu goddess of darkness. The system-lords are rude and difficult. Teal'c hates Cronus above all because his father, once his prime, was killed as punishment for failure and Sam believes he ordered Jolinar's execution. Thor explains the Asgard really bluff against the feudally divided Goa'uld as they must reserve their main forces for a far worse enemy in their own galaxy. The Goa'uld demand recognition of their race's superiority, the right to limit earth's technological development to any level they consider threatening and both earth's start-gates, the Secretary is inclined to advice the president to accept. Then Teal'c is found badly wounded, Cronus worse, with his symbiont dying. Yu and Nirrti want to take Cronus away immediately as he needs a sarcophagus but are retained at gunpoint. Teal'c wakes up and says they were attacked by an invisible third party, Sam proves a theory of deceit by Nirrti, who when exposed is attacked for it by Yu, who proves grateful as well as Cronus...

4Legacy

SG-1 discover nine Goa'uld corpses in a sealed chamber, Teal'c identifies the crest as the nine Linvris, minor rivals of the system lords. While reading a tablet containing page one of some war plan, Daniel unknowingly gets infected by a parasite, which gives him visual and auditive delusions back on earth. An epidemic of migraine causes the general to keep all SG-teams in the base for examination. Daniel was already in a padded psych ward cell when during a visit from the colleagues he hears Ma'chello's voice say the parasite has left to enter its real target, a Goa'uld: Teal'c, for whose symbiont it is lethal. During examination of the page turner which released the designer organism, Jack, Dr. Fraiser and Sam get infected by several parasites, only Sam is found immune, even able to kill it by hosting it. The race is on to find how and hopefully use that mechanism to save the other three infected ones...

5Learning Curve

The planet Orban, with Precolumbian Teotihuacan-culture antecedents and Aztec type pyramids, has made impressive scientific progress, and brings Sam a naquadah reactor to study; when she demands an instructor, Orban official Kalan surprises SG-1 by saying that he does not know what an instructor is, but 11 year-old Merrin stays on base to teach Carter. On Orban, Kalan's son Tomin, another 'urrone' (apprentice) is assigned to exchange knowledge about the Goa'uld with Teal'c and Daniel. SG-1 and Dr. Fraiser are astonished to discover the Orban urrones know neither fun nor school: a mass of useful new information is acquired while they are young and stored in the easily reproducible form of nanites, which are implanted in every Orbanian's brain after the urrone's 'averium', a coming of age ceremony at age 12, which extracts the knowledge from the individual and ends their ability to function mentally, so those children are 'retired' for life and from the active society. The Orbanians are furiously insulted by any suggestion to avoid an averium for the child's sake, yet Jack retains Merrin to let her experience how earth children spend their youth in schooling and play, offering it to her as an alternative to the averium, with a remarkable result...

6Point of View

The quantum mirror Daniel found in "There But for the Grace of God" brings to Area 51 an alternate Kawalsky and Dr. Carter from another reality, this time one where Sam never joined the military but became Jack's wife and the Goa'uld just overran earth. Dr. Carter begins suffering from temporal entropic cascade failure, a paradoxical effect of having two versions of the same person in the same reality and realises that she must return to her own reality or both Sams will eventually perish. SG-1 embark to the alternate reality to intercede and prevent the Goa'uld from conquering Earth before our General Hammond has the mirror disabled. The alternative Teal'c remained Apophis's loyal first prime, so the 'real' one can assume his identity to infiltrate the invading force but they are discovered and captured, but this only serves as the ideal diversion while the Sams also contact the alternate Asgard...

7Deadman Switch

While on a mission to recover a UAV, SG1 are captured by a Bounty Hunter working for evil System Lord Sokar. He tells them there is a bounty on their capture, but offers to let them go if they help him capture a Goa'uld. The Goa'uld turns out to be a Tok'Ra. Can the team persuade the Bounty Hunter to release the Tok'Ra, but prevent SG1 from being handed over to Sokar?

8Demons

SG-1 lands on a planet where a culturally 'medieval Catholic' community lives in fear of a demon of Unas's species, which regularly collects human sacrifices to Satan, in fact hosts for system lord Sokar's army. When Simon implores SG-1 to spare his beloved Mary and take him instead, they even nurse her chicken pocks. Simon hopes they are sent by God to deliver them from the satanic burden, but the canon who rules the village as 'spiritual' leader faithful to Sokar fears his authority challenged, which rests on his right to selected the 'damned soul' to be sacrificed, declares Teal'c a demon and incarcerates all SG-1. Witch-trial-type ordeals see the Jaffa 'proven' a demon and executed by drowning, Daniel refuses the canon's to leave immediately. When Teal'c's symbiont allows a resurrection even Sam hadn't expected, they are all designated possessed and sacrificed, yet Mary is also. Simon follows the Unas with a staff weapon to liberate them, but he's not alone...

9Rules of Engagement

SG1 come across another SG team being attacked by Jaffa. They offer to help but are shot by the SG team members. When they awake, they find out that the other SG team are Jaffa, loyal to Apophis, who are planning to infiltrate Earth. Can SG1 convince them that Apophis is dead before the Jaffa fight to the death?

10Forever in a Day

Responding to a help cry from Kasuf, SG-1 and more USAF wipe out a Goa'uld Jaffa guard to save most Abydonian slaves. When Amaunet turns her hand device on Daniel, he can't bring himself to shoot his beloved wife Sha're, but Tel'c saves him by fatally staff-shooting her; Abydononian funeral tradition squashes his hope of a sarcophagus resurrection. Crushed by grief, Daniel has apparitions by Sha're and once released from hospital resigns from SGC, claiming the quest for his wife was his reason to join; his former research assistant Dr. Robert Rothman succeeds him in SG-1; Jack is sure he'll be back. Sha're (or Ammaunet's posthumous manual spell?) keeps appearing to Daniel life-like, telling him to forgive Teal'c and together find their boy, who as Harsisis has all the Goa'uld knowledge in his genetic memory, punishable by death. Daniel agrees to return, but has his secret agenda too...

11Past and Present

On the planet Vyus, SG-1 discover an entire early industrial society suffering from collective amnesia since an unspecified event about a year ago known as the Vorlix. The most lucid local, scientist Ke'ra, develops an almost amorous relationship with Daniel while she shows the team the fascinating diary of a deceased scientist, which also mention a pesticide Dargol which had to be banned because it affected fertility and a 'visitor' named- Linea, who fits the description of the Destroyer of world SG-1 inadvertently helped escape (in "Prisoners") with them from a penal planet. Ke'ra and a Vyus couple, Orner and Layale, come to star-base where Dr. Frazer proves Ke'ra has Linea's DNA, and the amnesia is caused by a physical block in the brains caused by Dargol, which Linea developed into an experimental fountain of youth, which apparently suddenly went wrong. Manufacturing a medicine within a reasonable time, before ignorance ruins the planet, is hopeless without Ke'ra/Linea, but shouldn't she rather be incarcerated then given the chance to play another diabolical trick if she remembers her evil persona?

12Jolinar's Memories

Martouf leads a Tok'ra delegation with crushing news for Carter: her father Jacob/Selmak has been captured by Sokar and imprisoned on Netu, an Egyptian name for hell, on a moon of planet Delmal, from where nobody returns to suffer eternal torture, only Jolinar ever escaped. SG-1 mounts a rescue operation with Martouf, top-priority being any information Selmak can offer about Sokar's plan to subjugate the other system lords, an unprecedented threat for all humanoids in the galaxy. Teal'c must pilot a goa'uld ship and keep it in orbit as landing is impossible except by small pod, but first Martouf taps into Jolinar's memory, which is partially blocked by some trauma beyond physical torture. Only when they're down and in custody of Netu's lord Bynarr, Sam realizes he is the key, in a 'personal' way, but not voluntary as she thought. Sokar learns their presence from Bynnar and orders team and craft destroyed, but this also means there must be a way out. Bynarr's prime Na'onak has and is himself a major surprise...

13The Devil You Know

Now Apophis has revealed himself, he promises the prisoners to overturn Sokar, which requires extracting an irresistibly valuable secret, to which end he drugs Sam with the truth serum 'blood of Sokar' and implants a memory device plus the drug to torture Jack in the persona of his dead kid son and Daniel for the location of his Harsesis son; Martouf's love for Jolinar makes him betray the Tok'ra are on planet Etnac- a convincing lie, so Apophis's plan to earn Sokar's gratitude and then kill him when rewarded with the lordship of Netu is on a shaky basis... Teal'c must help the Tok'ra Aldwin prepare a nuclear weapon to explode the whole moon, as last chance to eliminate Sokar when his ship arrives, but decides to rescue SG-1 instead by flying in the path of the rings device to Sokar's ship...

14Foothold

After a vain search for Amaumet and the Harsesis boy on an unexplored planet, SG-1 is told there is a chemical leak and gets sedating injections in the infirmary. In fact star-base has been taken over by body-snatching aliens, as Teal'c and Sam discover, who are immune because of his symbiont and her Jolinar-remnants. Teal'c is captured while giving Sam the chance to escape; she meets with Colonel Harry Maybourne, who alas believes and brought the alien-possessed Jack and Daniel, who claim it's paranoia caused by the leaked chemical; during a flight back, Sam is able to see trough the game because of a 'flicker' and discovers it's done by two electronic devices to assume a human shape and voice. Meanwhile the real Jack and Major Paul Davis awake in an organic web where every human is tied into tentacles, soon meeting up with Sam and liberating Teal'c, in a hurry to try Sam's sound-idea before Maybourne sends in troops with orders to shoot and kill...

15Pretense

The iris brings surprise visitors to Starbase: the cat Schr?dinger as sign of friendliness, next Narim, the Tollan admirer Sam gave him to, who brings a unique invitation from the curia, the highest Tollan authority: an invitation to attend on Tollana, their new home planet, the 'Triad', a judicial ceremony, learning only there as requested by seeker (trial party) Skaara, to act a his his 'Archon' (attorney), a job jointly assigned to Daniel and Jack, his claim being his desire to be separated from the Goa'uld Klorel, Apophis's son, who refuses to give up his host; they crashed on Tollana after the Tollans destroyed both mother-ships Heru'ur sent after Klorel. Klorel's archon is the Goa'uld lord Zipacna, reason enough for Jack to be frantically mistrusting of the Tollan assurance all visitor weapons are automatically disabled. The third, neutral archon is Lya, a Nox; the Tollan Travell presides. While the human doctrine of birthright opposes Zipacna's claim of Ra's jurisdiction on Abydos and species superiority, like humans practice on lower animals, Teal'c and Sam fear his Serpent guards are locating the Tollan defensive ion guns to disable them, a nightmare scenario arrogantly laughed away by Travell, so Teal'c asks Ly'as for help. After Zipacna invoked that ruling against Klorel would be an effective death sentence, forbidden under Tollan law, Skaara's side that being a host is no valid life, a Goa'uld mother-ship is reported approaching; the Nox decides the sentence...

16Urgo

The SG1 team embark on a trip to visit a planet with an idyllic beach, but as soon as they step through the stargate, they find they are back in the SGC. They thought that they just left, but have been missing for hours. They soon discover that an alien device has been implanted in their brains and a being called Urgo reveals himself to the team. But no one else can see him and he is extremely irritating. Will they be able to extract him before they lose their minds?

17A Hundred Days

Whilst on a planet to negotiate a trade treaty, SG1 are shown a meteor shower called the 'Fire Rain' by the locals. They are very concerned, when one of the larger meteors enters the atmosphere in a near miss. Carter checks the astronomical data and Jackson the archaeological finds and they discover that the meteors may hit the ground with incredible force. They try to evacuate the villagers, but in the process, the meteors start striking the ground and whilst O'Neill is away trying to find some stray villagers, the Stargate is hit by a large meteor. The SGC try to dial back to the planet, but find that the gate is buried and is lying flat. Can Carter come up with a way to get back to the planet, or will O'Neill be trapped there forever?

18Shades of Grey

Whilst negotiating on the new Tollan home world, SG1 are refused any technical weapons help, so O'Neill steals a defence device. He returns to the SGC and is suspended by Hammond. Whilst on suspension, he is visited by Maybourne and told that there is a team off-world that unlawfully captures technology for Earth. He offers O'Neill command of this team. O'Neill uses the pretense of retiring off-world to leave through the Stargate. But once off-world, he meets Maybourne's team. Is everything as it appears though?

19New Ground

Whilst redialing old Stagate addresses, the SGC discovers that a gate that was previously buried has become uncovered. They send a probe through and find two archaeologists. However, when they travel through the Stargate, they find that it is located in a in civil war: one continent believes that the people were created by a Goa'uld, whilst their enemy believes that humans arrived from another planet - by the Stargate. O'Neill, Carter and Jackson are captured by the authorities and questioned, but Teal'c is wounded and blinded. Can he help SG-1 escape the hostiles and get back through the Stargate?

20Maternal Instinct

Master Bra'tac arrives at the SGC saying Apophis has attacked Chulak. Apparently the Goa'uld search for the Harsesis son of Sharee/Amaunet. Bra'tac believes that the child is in Keb, on a planet the Goa'uld fear too much visit; SG-1 and Bra'tac look there for the boy.

21Crystal Skull

The SGC send a MALP to a huge pyramid and inside they discover a crystal skull like the one Jackson's grandfather found many years before. SG1 visit the planet and whilst Daniel is looking into the eyes of the skull, as his grandfather did, an energy field envelops him. Teal'c fires his Zat at the skull, but Daniel has disappeared. Carter collapses and the team minus Daniel return to the SGC. Teal'c returns to collect the crystal skull, but will he be able to find Daniel?

22Nemesis

While taunting Carter leave means leaving to have fun, not staying behind for more research, Jack is suddenly beamed aboard the spaceship of the Asgar Thor, who explains he is dying, and his ship falling victim in the war against the Beliskner to replicators, an all-infesting kind of mechanical bugs which literally devour it to multiply, the transport and self-destruction mechanisms are now also disabled but their next target will be earth if they manage to land. Jack contacts SGC, asking advice and forbidding SG-1 to join him, but they do after the general overrules the colonel, assuring him they have a way back. After Sam makes sense of Thor's notes about the 'techno-bugs' and discusses them with him, she comes up with a plan to explode the ship and the bugs and escape by stargate, but it depends on meticulous timing and Teal'c placing explosives at the outside, which proves even more dangerous then it sounds...

1Small Victories

Jack's second attempt to take a fishing holiday is stopped again when the Pentagon sends USAF Major Paul Davis to call for SG-1's expert help after a Soviet submarine was invaded and its whole crew killed by the replicator which survived the crash of Thor's space-ship and multiplied; Washington needs it handled discretely. At the same time Thor, who is healed, arrives by star-gate to ask help in the Asgard war against the Biliskner which looks desperate, as they only learn from superior technology, so Thor asks 'dumber' help as primitive means like firearms do work; ironically Sam is the one sent with Thor, who shows her the most advanced Asgard ship, their first special war design, called the O'Neill. Jack and Teal'c go inside the submarine with regular troops, finding a whole nest with the survivor bug integrated in a queen; recovering Daniel stays above water with control, but proves valuable there, realizing the meaning of rust on the new bugs... Sam is deliberately not told all the Asgard now, but concentrates on out-smarting the replicators in their way of thinking to devise a trap, which comes at a price Thor is reluctant to pay: sacrificing the O'Neill without any guarantees...

2The Other Side

After 3 'impact' events against the iris, the SGC is contacted by humans that are at war and under attack. They plead for help and SG1 visits them. They are technically advanced, living underground in bunkers with much of their population in stasis, protected by shields and remotely piloted aircraft, but all is not as it seems and Jackson asks questions that elicit disturbing answers.

3Upgrades

The SGC is visited by Tok'Ra called Anise who brings some armbands used by the soldiers of a long extinct race, supposed to increase the abilities of the wearers. O'Neill, Carter and Jackson put the armbands on and it improves their physical strength, but it also causes them to make rash decisions. can they get the armbands off before they cause their deaths?

4Crossroads

An old love of Teal'c, Chulak temple priestess Shan'auc, arrives at the SGC saying she can communicate with her symbiont. Teal'c does not believe her, until he tries and sees that it is true. They travel to the Tok'Ra, as Shan'Auc's symbiont needs to blend with a host, but isn't it really still a Goa'uld?

5Divide and Conquer

When an SG member tries to assassinate the Tok'Ra leader, it is believed that some of the SGC have been converted into za'tarc - programmed assassins. The Tok'Ra Anise comes to the SGC with Lantash, to try and test the SG members. But the za'tarc detector suggests that O'Neill and Carter are actually za'tarcs. Is this correct and is there another za'tarc at the SGC?

6Window of Opportunity

Colonel Jack O'Neill and Teal'c have a recurring case of d?ja-vu, but it's much worse, they really recall what happened ten hours ago on SG-1's mission to a planet where a device at an altar near its star-gate throws them back in time, yet Daniel nor Sam recollect anything so SGC refuses to believe them, they're tested, found medically OK, the general calls the mission off when Sam feels it might actually be some time-distortion, but that doesn't work. They learn to be more convincing, so they can go to the planet, but there a certain Malikai proves a problem. Their only hope is to help Daniel decipher the inscriptions on pictures of the altar over many, many time-loops, after Sam helps them make sense of what must be happening; meanwhile Daniel gives them the naughty idea they can get away with pretty much any pranking, as everything reverts to normal unharmed anyhow...

7Watergate

When an attempt to dial out a wormhole fails, the SGC discovers that the Russians have a Stargate and it won't shut down. Together with a Russian expert, SG1 parachute onto the Russian base. They discover that the Stargate is the one lost on Thor's ship. Everyone in the base is dead and some mysterious water taken from a water planet is missing. Three of the team travel to the Waterworld by minisub. Then O'Neill discovers a frozen Maybourne in the freezer.

8The First Ones

Whilst on an archaeological dig at the original Goa'uld home world, Jackson is captured by a young Unas. He tries to communicate with it and slowly builds a rapport. Meanwhile, SG1 comes to the planet to find Jackson and they soon realise that some of the SG members there may have been taken over by Goa'uld. Will they be able to discover which ones in time to rescue Daniel.

9Scorched Earth

SG1 are celebrating with the Enkarans they settled on P5S-381, but they receive word that a huge spaceship has destroyed the nearby village and is slowly moving towards them burning the ground as it goes. SG1 try to communicate with the ship and find out that it is 'terra-forming' the planet for a long dead race. A biomechanical lifeform in the ship, tells SG1 that the Enkarans must leave. But they cannot, because they would die. Can SG1 solve the problem in time?

10Beneath the Surface

The SG1 team awake to find they have lost their memories. They believe they are workers in an underground power station. They are told that they are helping to preserve life during an ice age. In truth they are slave labor to a huge domed city above and when Teal'c starts to recover his memory and is given another amnesia treatment he forgets his Kelnorim and starts to die. Will the others recover their memories in time to save him?

11Point of No Return

SGC is contacted by Martin Loyd, a conspiracist who knows too much about the Stargate to be ignored, so how did he learn? When O'Neil meets him and fails to put him on a wrong track, Martin believes to be an alien and offers to show his spaceship but fails to find it. Martin knows about the Stargate - how come he has a gate address and is he being drugged by others? Using police surveillance equipment, Daniel and Sam find Martin's home, with psychiatric medication and a diary. Dr. Fraiser finds his drugs, prescribed by psychiatrist Dr. Peter Tanner, were laced with unidentified chemicals, possibly to cause his delusions. Martin finds Jack and Teal'c and demands to be 'returned home' trough the Stargate, even wrote down a seven-sign address from a vision, and finds the clearing, but says the craft they find is a mere pod, there must be a much larger ship. Meanwhile Tanner and two sinister cahoots who refuse to identify themselves capture Daniel and Sam, and threaten them with torture. Martin's memories start to fit a Goa'uld enslavement scenario. Tanner's trio captures Martin; Jack and Teal'c tail them, but more surprises await...

12Tangent

O'Neill and Teal'c test-fly the experimental spaceship X301, created from two captured Death Gliders. While they attempt a test run in the atmosphere, the craft flies into space. A message from Apophis plays to say that the traitors who took his property would die in the cold of space. Can the SGC find a way to bring them back, or will they die drifting ever further from Earth?

13The Curse

Daniel attends the Chicago funeral of Dr. Jordan, the archeology professor whose most brilliant assistant ever he was before leaving to pursue his far-fetched alien-Egyptian theory and join the Stargate-program, but smells a rat after an explosion is his lab. Daniel brings in the team, soon realizing Jordan's last Egyptian expedition stumbled upon a unique grave, from which pieces are missing, actually holding the remains of at least one Goa'uld divinity: Osiris, god of the aftermath and first Pharaoh. Dr. Frazier's analysis of a canopic [mummy entrails-container] jar finds an amazingly well-preserved symbiont, but the trace of its counterpart reveals one of Jordan's present assistants, Dr. Steven Rayner, whom he suspected, took a golden amulet to open the unique tomb and fell prey there to the other goddess, Isis, who actually turns out to be incarnated in the other assistant, Dr. Sarah Gardner, who remains quite alive and murderous...

14The Serpent's Venom

While pleading the cause of freedom trough rebellion among the Jaffa warriors on his home planet Chulak, Teal'c is betrayed as sacrilegious sholva (traitor) by Rak'nor, son of a Jaffa friend of his father, and handed to Terac, the torturer of system lord Heru'ur. Ignorant of his fate, the other SG-1 members join Jacob in a risky attempt to take hold inconspicuously of a space mine by Tok'ra ship piloted by Jacob, the manual of which Daniel must decipher in Fenician so Sam can reprogram it. Only when it's on course to Apophis's spaceship, the expedition learns Teal'c is being offered as confidence-building present from Heru'ur to cement an alliance against the other system lords, which would make the Goa'uld threat more dangerous then ever. An attempt to save Teal'c, by intercepting the rings beaming like he did for them on Sokar's penal moon, not only fails, Apophis's cloaked fleet -an unpredictable first- overpowers Heru'ur. However Teal'c's resistance to torture and clear conviction that Goa'uld are no gods finally convinces Rak'nor, who now bravely acts...

15Chain Reaction

General Hammond mysteriously retires from the SGC and a new general is brought in, who breaks up SG-1: Daniel and Sam are scientists, Teal'c is with SG-3 and O'Neill commands a new SG-1. O'Neill tries to convince Gen. Hammond to return, but he finds out that someone ordered Hammond to leave or they would hurt his grandchildren. While the others are occupying the new general, O'Neill tries to find out who that "someone" is. Thereto he must place his trust in the one person he hates most: Maybourne.

162010

In 2010, Robert Kinsey is president of a brave new world since he concluded the alliance with the Aschen, a race discovered by SG-1 which lets humanity enjoy its far advanced science and technology, including a vaccine against aging. Sam is now a civilian scientist, married to ambassador Joe Faxon, whose only worry is failing to get pregnant. When she double-checks the Ashen doctor Mollem's computer with Dr. Fraser, who felt superfluous given superior medicine, they discover human fertility is down 90% worldwide in three years. Sam, Daniel and Teal'c turn to retired general Jack, who always warned against handing over technological control, for a daring plan to turn the clock back like general Hammond did once, sending a message to their past with the exact time of a solar flare, which Sam can calculate using the Ashen computer. Only one ingredient is out of their reach: the GDO device to control the Stargate's iris, which is in the White House. Sam implores her husband Joe to steal it, but he has a secret as well as sincere objections...

17Absolute Power

When a "chosen" boy found on planet Abydos is brought to SGC, he sends a telepathic message, causing Daniel Jackson's personality to undergo disturbing changes. Will the rest of SG-1 be able to solve the mystery of the boy's origin before becomes a power-hungry warmonger?

18The Light

SG-5's Lieutenant Barber commits suicide by jumping into the Stargate shortly after a mission on a planet where a since about 200 years abandoned Goa'uld palace is studied by Daniel, who soon develops violent mood swings and is committed to hospital with a neurotransmitter brain condition, presumed fatal after all other SG-5 members die; alas meanwhile SG-3 has visited the planet, finding only the light installation Daniel reported as particularly fascinating and human teenage boy Loran, who hid for Daniel's expedition but now tells Jack he was left there by his parents, scientific researchers. Back in SGC, Jack also develops symptoms. Sam and Dr. Frasier conclude it must be some addiction linked to the light, so when Daniel is nearly terminal Jack, who might not have been exposed too long himself, must bring him back. Jack insists to try turning off the light, and leans on Loran, who is looking for a father-figure, even gives Teal'c an early 'birthday present', but indeed has a dark secret..

19Prodigy

The chief of staff visits SGC and meets Jack, while Daniel is on a mission. Sam is giving a physics lecture at the Airforce Academy, where she meets and is intrigued by the theoretical insight of US Air Force cadet Jennifer Hailey, academically her successor but a pest in terms of conduct and attitude. When Hailey is about to be expelled for violence against another cadet, Sam convinces the Academy and general Hammond to give her a motivating taste of Stargate work. So they join Jack and Teal'c who are on a planet's moon as security escort to three scientists, but soon find a life-form consisting solely of buzzing lights isn't as inoffensive as it sounds. Sam and Haley come up with incompatible theories; time is running out with the fuel for the generator they need for the only known defense, so Jack makes a barely educated gamble...

20Entity

After a MALP goes out of remote control, even flying wild, an energy burst during an emergency Stargate shutdown causes serious damage in SGC, and wounds operator Sergeant Siler; Dr. Frasier keeps SG-1 down for check-ups. It soon becomes clear a 'computer program' has entered trough the wormhole, and is taking over the SGC computer network; even after Sam shuts it down, it reemerges, constantly requiring more memory. It not only 'nests' in a hardware constellation it creates, but even manages to take over Carter's brain, and communicates. It's a non-corporeal life form, whose entire home was damaged by a virus caused by the MALP radio waves, and believes its best survival chance is inside Sam, as the humans won't sacrifice her; true soldier Jack however decides to play hardball...

21Double Jeopardy

On planet Juna, SG-1 minus Daniel gets a hostile welcome from the local warriors leader Darian, who seems incredulous they even dared to return. They loyally deliver Sam and Teal'c, the particularly hated 'sholva' (Jaffa traitor) to Cronus (who took over as system lord after SG-1 helped chase Heru'ur) and told them to bury the Stargate. Cronus orders Darian to decapitate Daniel by staff weapon- to find his head is robotic. Cronus's obvious astonishment makes Darian doubt his divinity. At SGC, Harlan urge them to go on a mission. The master robot-creator tells them that the robot versions he created need to recharge after 48. In order to prevent the Goa'uld picking their mind copies, they reluctantly go. Darian now joins them, but feels most of his people won't dare challenge Cronus ever. The two Teal'cs concentrate on revenging the original's father by attacking Cronus recklessly, while the Sams and Jacks deal with the military problems and overthrowing the Goa'uld rule.

22Exodus

SG-1 return to the Tok'ra planet to help them move to a safer planet. Tanith hasn't heard the news of moving to a new planet and SG-1 decide it's time to tell him that they've known all along that he was a spy of Apophis. Tanith escapes his prison and leaves the Tok'ra base. He signals Apophis. When the Tok'ra hear word of this, SG-1 plans a trap. Move the Stargate to a ship and send it towards the sun which will cause a nova explosion, destroying Apophis and his army. Jacob Carter volunteers to send the Stargate to the sun. SG-1 goes with him. As soon as the Tok'ra have left, SG-1 takes the Stargate onto their ship. Soon after the Stargate has been sent toward the sun, Apophis and his ships show up. Two gliders are sent down to the planet to pick up Tanith. O'Neill and Teal'c head toward the planet in their glider and stop the ships from reaching Tanith, but their glider gets hit as well and they land back on the planet. A Gou'ald ship sees all this and heads down to the planet. The Jaffar soldiers pick up Tanith and kill Teal'c. They bring his body aboard, leaving O'Neill alone on the planet. SG-1 picks him up and Jacob flies the ship into hyper speed just as the Stargate hits the sun and explodes. Apophis's army is destroyed. But the effects of the explosion catch up with SG-1's ship and knocks it off coarse. They end up in another universe. Jacob says it will take them over a hundred years to get home, even with hyper speed. Soon another ship comes out of hyper speed. It's Apophis's mother ship.

1Enemies

The surviving members of SG-1 are lost in the unknown darkness of space and are being chased by Apophis. But before Apophis destroys them, an unknown ship attacks and gives SG-1 a chance to escape. Apophis's mother ship finds them again, but they soon find out that there are no lifeforms aboard. Instead they find an army of replicators aboard the ship and the self-destruct system has been activated. They escape the mother ship just as it explodes. Soon after, they receive a message from Teal'c who has been brought back to life and has escaped the attack on the mother ship. But SG-1 soon finds another problem: Teal'c has been brain washed.

2Threshold

3Ascension

SG-1 finds a weapon on planet 616. As Carter is inspecting it, a spirit alien interacts with her. But Carter passes out. So the alien follows them back through the Stargate. Hammond believes there may be something wrong with Carter and sends her home. The alien takes the form of a man and calls himself Orlin. He lives with Carter for a while and the rest of SG-1 think she's going crazy. In time Orlin and Carter fall in love. But the pentagon finds out about the alien and surround Carter's house.

4The Fifth Man

In escaping a large contingent of Jaffa, SG-1 is forced to leave behind Jack and Lt. Tyler, a new member of the team. Back on Earth no one can recall Lt. Tyler, so Sam, Teal'c, and Daniel must find a way to save Jack while they are quarantined. Meanwhile Jack and Lt. Tyler struggle to escape the enemy Jaffa.

5Red Sky

After a rough ride through the stargate to P39-865, the sun of that planet turns red. Carter deduces that an override of stargate protocols allowed them to create a wormhole through the sun, starting a reaction that will cause the sun to die. SG-1 must now make up for their mistake or P39-865 will become incapable of supporting life.

6Rite of Passage

When Cassandra collapses at home, she is taken to the SGC for treatment. A retrovirus is causing her to emit an EM field and she expresses a need to return to her planet for an initiation ritual. SG-1 investigates and finds a Goa'uld laboratory, probably having belonged to Nirrti, meant for experimentation on the planet's population. They find that the ritual is part of the experiment, a time when Nirrti studies her subjects and cures them when she is done. SG-1 has found a way to cure Cassandra, but now all that remains to be found is Nirrti.

7Beast of Burden

When Chaka, the Unas Daniel previously befriended, is captured by humans bearing Goa'uld weapons, SG-1 go to rescue him. There they find a society in which Unas are treated as slave labor and, in an attempt to free Chaka, Jack and Daniel are taken prisoner.

8The Tomb

SG-1 teams up with a Russian task force to investigate the disappearance of a Russian SG team on P2X-338. They discover that the Russian SG team released a creature that killed Marduk, a Goa'uld, in his sarcophagus. SG-1 must trust their Russian partners in order to escape the ziggurat alive.

9Between Two Fires

After the death of Omoc, the Tollan assert that they are now ready to trade technology with the Tau'ri. Negotiations go smoothly, a little too smoothly. SG-1, with the assistance of Narim, investigate the death of Omoc and the Curia's deception of the Tollan people.

102001

SG-1 comes in contact with an alien race called the Volians, a peaceful agricultural race, who introduce them to an advanced race called the Aschen. With the promise of advanced technology from the Aschen, negotiations are opened up and the SGC prepares to go to one of the possible Aschen home world. When it it realized that the home world might be the one mentioned on a note sent trough the stargate a year earlier, the team becomes suspicious, leaving Daniel and Teal'c to explore a buried city on the planet. As the negotiations continue despite the warnings of O'Neill, Daniel discovers a secret about the Volians past with the Aschen that could have deadly consequences for Earth.

11Desperate Measures

Carter gets kidnapped and taken to an abandoned hospital where two doctors work to study the remains of Jolinar. She finds out that they have a Gou-ald, taken from the Russians, and are planning to put it inside a man named Adrian Conrad, to heal his sickness. They need Carter to tell them how to get the Gou-ald out after he's healed. O'Neill believes the government is involved with Carter's disappearance and contacts Maybourne. Together, with Daniel and Teal'c, they find Carter but also find out that the Gou-ald has escaped inside Conrad's body.

12Wormhole X-Treme!

A strange ship is headed towards Earth, and the SGC suspects that Martin Lloyd and his companions may have something to do with it. O'Neill is sent to speak to Martin and is assigned as a military consultant on Martin's new show, "Wormhole X-treme!", which uncannily resembles SG-1 despite Martin once again losing his memory. His former shipmates stall Carter and Daniel by throwing them off the trail and into the hands of the NID.

13Proving Ground

It's SG-1's turn to start testing a quartet of Air force cadet prodigies for SGC recruitment. After an imperfect performance by their kids, Sam pleads their potential but Jack is most critical, especially because cadet Lieutenant Grogan was left behind (pretending to be wounded). A new problem arises (aliens try and take over SGC) and the cadets are unsure whether this is staged or not. This time their CO, Lieutenant Elliot, proves himself to be a born leader and gives everything he has to get the job done. They almost seem to have pulled it off until Haley pulls a "Sam-stunt" which changes the scenario for the worse again.

1448 Hours

Teal'c is trapped in the stargate's memory after the the stargate on the other side is destroyed. The Pentagon gives Carter and physicist Dr. Rodney McKay 48 hours to try and find a way to get Teal'c out. Meanwhile, Daniel and Major Davis are sent to Russia to negotiate for use of the D.H.D. and Stargate the Russians have to keep the SGC operational. O'Neill, with the help of rogue NID agent Harry Mayborne, investigates NID boss Colonel Frank Simmons whose captured Goa'uld, using Adrian Conrad as a host, may hold the key to saving Teal'c.

15Summit

16Last Stand

As the Goa'uld summit continues, Daniel finds himself face to face with Osiris. He fools him in the same fashion as he did with Yu, but cannot bring himself to cause the death of Sarah, Osiris's host. He remains to uncover information about the unknown master of Osiris.

On master Bra'tac's advice, SG-1 agrees to visit and help the Jaffa rebels training camp of K'tano, former First Prime of Imhotep, a Goa'uld they soon find wasn't even an actual system lord. While the humans grow increasingly suspicious of his cruel and wasteful training methods, Teal'c considers them traditional and agrees to be recruited for a mission to eliminate the system lord Yu-huang Shang Ti, aboard whose ship an uprising is planned. The team does a great job in the camp, demonstrating the value of earthling weapons the Jaffa originally scorned, but learns there is more and worse to K'tano.

19Menace

20The Sentinel

SG-1 is sent to planet Latona, which is under attack from Goa'uld system lord Svarog because its Ancient defense system, the Sentinel, stopped working after Maybourn's rogue NID team secretly assembled and reassembled it. Colonel Sean Grieves and his rude assistant, lieutenant Kershaw, are taken from death row to join the rescue mission to repair it and/or evacuate the Latonians. Planetary leader Marul refuses to accept facts, despite the rule of terror already being installed by a Jaffa battalion, even when Svarog's starship arrives and Jack insists it's time to leave with or without the Latonians, claiming the Guardian must be alive and alert as a flame signifies. When Sam joins the repair team, which Daniel helped pass the ingenious protection field, the gruesome story of how the NID thieves got to it the first time proves crucial.

21Meridian

SG-1 arrives on P9Y-4C3 in the country of Kelowna, one of three countries in an uneasy state of cold war. Sg-1 investigates the country and discovers that Kelowna's technological level is similar to that of the United States in the 1940s, and that several Goa'uld artifacts were found near the planet's stargate. From the artifacts they find a powerful Naquadah variant called Naquadria, which they are turning into a weapon. An accident leads to the Naquadria nearly exploding and Daniel Jackson saving millions from certain death, but he exposes himself to dangerous levels of radiation. Back at the SGC, Daniel lays dying until Oma Desala, an ascended being the team met on the planet Kheb, appears to him and offers him the chance to ascend.

And Anubis left it well guarded...

3Descent

Stargate Command discovers a Goa'uld Ha'tak in Earth orbit. Exploring, they discover it is the ship where Anubis briefly imprisoned Thor. At some point, Anubis' forces set the self-destruct and abandoned the ship, but something has halted the destruction and brought the ship to Earth.

Stargate Command is faced with giving them superior weapons or "forcing" them to use a deadly device. But Dr. Keiran might have an alternative - a mysterious underground only he can contact who can overthrow the government and bring peace - if that government doesn't find them first, and if Keiran is telling the truth...

8The Other Guys

Told from the point of view of a stereo-typical scientist, Jay Felger (in love with SG-1).

Things turn south when the news crew arm themselves and hold the Prometheus, as well as Sam and Jonas, hostage.

12Unnatural Selection

The Asguard home galaxy has been over-run by the replicators, and they ask for SG-1's help. The Asguard believed they had trapped the replicators with a device that would slow down time, but it seems to have failed. They need SG-1 to enter replicator infested space, find the time dilation machine and reset it. When SG-1 land at the designated point, they meet 5 individuals, who control the replicators. The others reveal that they are an evolution of the replicators - composed of micro-cellular replicator blocks, and modeled on Reese, who created the original replicators. These others have reset the time machine so that time is moving more quickly within this area of space - to allow them to evolve and build an enormous army that can invade the rest of space. The minds of the team are probed by the first 4 others. However, the last member of the others (called Fifth) seems reluctant - he is described as weak by First, the leader of the replicators. He was an attempt to model Reese more fully, but the mistake will not be repeated. Carter senses his reluctance to probe her mind, but invites him to do so - and they agree a plan. Fifth will reset the time dilation machine to run slowly, and he will escape with the SG team. While time is passing slowly for his brethren, the Asguard will have hundreds of years to fix the mistake in the others. Fifth has to leave later than the SG team to avoid arousing the suspicion of the others; Jack orders Carter to set the timer on the device to activate earlier than Fifth has been told. SG-1 escape successfully as the time dilation device reverses the trend within the area of space, and makes time run much more slowly. However, Fifth is caught by his brethren, and realises that Carter had broken her promise not to leave without him. Carter and Jonas regret using Fifth's humanity against him, but even though Jack seems uncomfortable, he declares that Fifth wasn't human, and they made the only correct choice.

In an attempt to observe what may be an undiscovered black hole, Carter is sent to the wrong planet. She returns with this information and begins diagnostics on the dialing computer. When they find that nothing is wrong on their end, Carter theorizes that the gate is keeping people out by redirecting them to a random planet. She cracks the code keeping them out and SG-1 goes to investigate the planet.

10The Fourth Horseman: Part 1

A prior has convinced Gerak, leader of the Jaffa Nation, into following Origin. He is attempting to make Origin a state religion for the Jaffa. Teal'c and Bra'tac attempt to make a case against the Ori, but to no avail. Meanwhile, a "prior plague" has breached SGC and spread to the rest of Colorado.

11The Fourth Horseman: Part 2

The plague continues to spread among the US population and the President has quarantined the nation. Teal'c is pleading with the Jaffa High Council to reject Origin, but Gerak arrives, having been transformed by the Ori into a prior. Cameron and Daniel seek the blood of the prior that caused the plague in order to cure it, but have once again been captured by the Sodan.

12Collateral Damage

13Ripple Effect

Multiple SG-1 teams begin coming through the gate, each one from a different parallel universe. Carter teams up with Martouf (Tok'ra), who in his reality joined the SGC, and Kvasir (Asgaard) to try and figure out a way to repair the damage that was done so that more alternate SG-1 teams do not become stranded.

14Stronghold

Leader of the Hak'tyl and their representative on the Jaffa High Council, Ka'lel has fallen in with those who work against a democratic Jaffa nation. Things worsen when she incapacitates and turns a well-spoken brother Jaffa who promoted democracy. Bra'tac comes to Hayes and SG-1 for help in finding a now missing Teal'c and uncovering the shadowy dealings in the Jaffa High Council. On Earth, Mitchell gets an old friend of his into a hospital where alien-based technology is used; hopefully, the advances they have made will be able to cure what ails him.

15Ethon

A contact within the Rand Protectorate comes to Earth with news that the Ori have given his people a superweapon to use against the Caledonian Federation in exchange for their conversion to Origin. SG-1 plans to turn the people from their newfound religion and destroy the superweapon.

16Off the Grid

On a mission to trade in a promising corn type, SG-1 is taken captive by Worrel, a Lucian Alliance underling, who also holds them erroneously responsible when their stargate disappears (as on several planets). General Landry works on Nerus's appetite for food and freedom to find out that the thief is Ba'al, who plans not only the ransom but to start a new Goa'uld empire. After the Odyssea rescues SG-1, SGC and the Alliance try to take on Ba'al and each-other.

17The Scourge

The SG-1 members grumble at the "honour" to host some international representatives of a powerful commission on a tour of a research base on another planet. Suddenly a project concerning voracious beetles intended to control an addictive plant they hardly deemed worthy half a minute suddenly turns dangerous: once fed a bit of meat, they prove unstoppable carnivores, escape and cause the base to be automatically quarantined, and later even to self-destruct - the surviving humans are surrounded, without means of communication, so earth will presume them dead and according to standard-protocol must launch a neuro-toxin to eradicate all life on the planet...

18Arthur's Mantle

When Samantha finally manages to start a device made by Merlin, it unfortunately renders her and colonel Mitchell invisible by transporting them to a parallel dimension. They must wait to be able even to manifest themselves till doctors Jackson and Bill Lee figure things out from the display the device presents in the language of the Ancients. Meanwhile Teal'c and SG-12 travel to the planet where a whole Sodan village is exterminated by its own hero Volnek, who was turned evil by a prior as a punishment for their 'disrespect' to the Ori - and find he sabotaged the portal (Eye of the gods) they need to get back.

19Crusade

As a result of a communication technology simulation Sam didn't even expect to work, Vala is able to possess Daniel's body long enough to tell how she awoke on an Ori-devoted planet, where she married the kind native Tomin when realizing she was pregnant although she couldn't imagine how or by whom, but found out a prior healed his old crippling wound so he could be conscripted to a huge army the Ori were preparing, while building a large fleet, for a crusade against the unbelievers. Meanwhile on earth, the Russians announce they won't prolong the treaty to lend the Stargate to the US, but start their own program, but general Landry guesses right that's only to press another demand... Vala continues the village's apparently dictatorial leader is actually the head of the resistance, which plans to sabotage the whole Ori-war effort, but overhears a prior tell Tomin he's infertile...

20Camelot

Since the weapon Merlin once devised against ascended beings seems the human race's best change to resist or even defeat the Ori, SG-1 travels by stargate to a medieval society in a place called Camelot where the local Arthur epic (differerent from earth's romanticized traditions) confirms its location should be found in a forbidden library guarded by a Black knight. When they are beamed up to earth's super-star-ships about to try stopping the Ori-fleet passing a super-gate, Daniel and colonel Mitchell decide to have themselves beamed back inside the library, but on neither front things go as expected...

1Flesh and Blood

Vala 's daughter is born healthy, but is immediately taken away to be raised as Orici, a 'baken in the darkness' to use the knowledge of the Ancients for the Ori-fighters against the infidels, and grows at an incredible rate. In an attempt to establish maternal influence, Vala calls her Adria, not telling that she's named after her wicked stepmother. The disastrous battle against the Ori fleet has destroyed or disabled most of Earth's star-ships. Just rescuing Sam drifting in her space suit is a terrible task, even with Kvasir's help. Teal'c is captured and tortured by the Lucian Alliance, which threatens to attack them. When the Ori fleet is signaled near Chulak, Col. Mitchell and Sam join the remaining Jaffa in a desperate counterattack. The missing Daniel turns up with Vala, and they decide to attempt turning Adria against the Ori.

2Morpheus

When Dr. Daniel Jackson ascertains the planet most likely to contain the Holy Grail-weapon which hopefully can defeat the Ori, Colonel Mitchell, Sam, Teal'c and Dr. Reimer search there in caves, but the only thing they discover is that the legend's mysterious 'curse' is actually a fatal parasitic disease which infects them- their only hope is to identify local wildlife's immunity. Back on the base, Daniel convinces General Landry that, although the Pentagon wants to exclude Vala, her unique knowledge can be invaluable, so she is extensively tested.

3The Pegasus Project

SG-1 learns that the whereabouts of Merlin's weapon (which should be able to defeat the Ori) is most likely on Atlantis, Daniel and Vala visit Earth's base team there. Meanwhile, its scientific top brain Dr. Rodney McKay is detailed back on the Odyssey with Lt. Colonels Sam Carter and Cam Mitchell, who are trying to reroute the super-Stargate through which they fear the Ori are about to send reinforcement ships, despite the danger of using nuclear explosions so close to a black hole. Daniel gets answers from the database, but figures out they don't come through a hologram but from an ascended Ancient: Morgan le Fay!

4Insiders

The SGC-base is approached by an al-kesh glider which lets itself be taken down, so they can capture Ba'al, who offers to exchange the necessary information to find Merlin's weapon for human help to eliminate his clones, which want to kill him. They mistrust his story, as does NIS-agent Malcolm Barrett, who however fails to take over the investigation. Since the captive might actually be a clone, several missions to different planets retrieve and capture all clones, but which is the real Ba'al, and what are his true intentions?

5Uninvited

General Landry plans to teach SG-1 how to relax in General O'Neil's log cabin while Jack is in Washington, but Daniel Jackson can't wait to consult an aristocrat's private library in London on Merlin. Meanwhile, Sam and Vala join Teal'c on P9J-333 where a mysterious monster devours all humanoids, as on several other planets which were recently visited by SG teams. Landry is left alone with Cameron Mitchell, who finds this rather uncomfortable. Dissection of a monster victim reveals it implants a centipede-like parasite, which transforms otherwise harmless indigenous species. Carter figures out it was spread by the Sodan cloaking device, but one is missing, and the suspect is probably after Landry and Mitchell, who find similar victims near the cabin...

6200

On General Jack O'Neil's personal recommendation, his -unwilling- former SG-1 mates are ordered to advise Hollywood production executive Martin 'Marty' Lloyd on a 'slightly ridiculous' version of the Stargate operations. The brainstorming proves rather unsatisfactory for both sides, despite repeated recourse to personal -often self-flattering- imagination and various real experiences, so the team members are relieved when General Landry calls them, as promised, for a mission, but just then the Gate breaks down temporarily. Marty also gets discomforting phone calls, and even more preposterous alternatives are considered, 'til an apparent "deus ex machina" appears...

7Counterstrike

On a planet where thousands were embracing the faith of Origin, a single wave of energy -destroying only living tissue- kills them all and the Prior. General Landry hears from Master Bra'tac, who is out of favor with the new leadership, and then its chief Se'tak, that it was ordered by the Jaffa council which intends to stop the Ori at all cost, using the ancient weapon from Dakara which successfully eliminated the Replicators. Teal'c and Mitchell on the empty Ori ship are captured by certain members of Bo'rel's armed Free Jaffa force; Daniel and Vala too, but their Jaffa captors fall prey in turn to Vala's evil Ori-daughter Adria, the sole survivor from the force wave. Against Landry's advice Se'tak orders to use the weapon at full power, which should destroy the planet and all ships around it, from which the Odyssey can evacuate the SG-1 members using the rings just in time, but it has no effect on the Ori ship, which in turn fires on the weapon on Dakara...

8Memento Mori

When Vala has a dinner with Daniel, she is kidnapped by the Trust, interrogated, and dumped with almost total amnesia, as waitress in a diner, where she does however demonstrate to have retained her fighting skills when a robber has the misfortune to come during her shift. Even after Daniel figures out which Goa'ulds on Earth -including Athena, and especially Ba'al- can be involved, it proves difficult to retrieve her. And when Mitchell does, she suspiciously takes him captured, badly wounded.

9Company of Thieves

While Lt. Colonels Michell and Carter are aboard the Odyssey, it hits a minefield and loses contact with Earth. They are captured by the Lucian Anateo, who kills the ship commander Emerson, and ultimately wants to replace Nethan, whose leadership of the Lucian Alliance is highly contested. The other team members have no starship available, but Vala 'finds' a lousy Goa'uld craft and, with Daniel, tracks the Odyssey's signal to her dodgy acquaintance Shamus, only to be trapped there and brought to Anateo, but escape in a Ha'tak vessel. Col. Mitchell uses a hallucinogen to make Nethan believe he is the mysterious Lucian Kefflin, finds Teal'c a captive and 'takes over' his torture, but is recognized by a space pirate Tenak who knows him as a bounty-hunter and just wants a cut...

10The Quest: Part 1

A dream reveal to Vala Morgan Lefay's clues to three planets must be combined to one Stargate address containing symbols for each, and only one qualifies- when they arrive, the local medieval society tells them a week earlier Ba'al was there, and warns nobody ever returned from the quest. The arrival of an Ori force to impose conversion convinces the local library's guardian Orsic, who shows a parchment with cryptic instructions for the Arthurian quest based on five virtues, to help them look for the Sangrail. The first obstacle is a maze through a time distortion field, which leads them to Ba'al, already trapped for three days by a chest which contains nothing, but releases them if everyone puts something in it. Daniel then realizes Orsic is not a local but a disguised Ori, and indeed it's Adria, who decided to enlist them since the prophecy requires searchers of pure hearts, so they solve the next riddles together, practicing each of the virtues...

11The Quest: Part 2

The team hadn't counted on a real dragon as guardian, 'til one flies there, breathing fire- however Daniel thinks it's a hologram, and the Sangraal probably isn't a real object either- meanwhile it follows them outside. Ba'al admits not to know its secret name, while Daniel believes that that probably holds power over it; while they guess, Cam thinks of luring the dragon to blow it up, but the explosion barely impresses its digestion; Daniel makes it disappear by using Morgan LeFay's name in Ancient. They find it had guarded the frozen 'grave' of the realm's arch-magician 'Myrrdin', but Vala accidentally triggers a mechanism which revives Merlin, but also transports the whole room to another planet. Merlin seems to confuse them with Arthurian characters, but once convinced they are on the same side, triggers a mechanism to transport them to still another planet, alas again without a working Stargate exit. Merlin dies at his mind-connected device, wishing them good luck and referring to one last task. Ba'al's programming skills now seem their only chance. Daniel tries the device himself, but is knocked unconscious. Then Adria's search for them -each time a bit quicker, one planet behind them- is visible on the Stargate dial, Merlin's corpse disappears, and they are again transported to another planet. Daniel awakens with valuable memories from Merlin, and tries to construct the Sangraal weapon using the device again in exhaustingly intense phases and finds it also gives him magical powers. Before he can finish the work (which damages his mind) Sam and Ba'al repair the device and escape, just while Adria's Jaffa troops arrive, but she captures Daniel...

12Line in the Sand

When an entire people may suffer the fatal wrath of a Prior of the Ori for not converting, General Landry orders Carter to try out an experimental device based on Merlin's technology to transport their whole village. The test works, but before they can activate it on a sufficiently large scale, an Ori force takes the village, wounds Sam and kills villagers near the Stargate before Vala's very eyes. Her husband, Tomin, captures her but claims to not love her. He is ordered, as punishment for being deceived by her, to re-educate her. Sam and Cam are able to activate the functioning part of the device, so their building is cloaked from the Ori, who threaten the village leaders and discover and arrest Teal'c. Even after the remaining villagers bow in submission, the Prior decides to destroy everyone since he couldn't find Sam, which makes Tomin doubt his faith, inform Vala, and confront the Prior. The villagers want to sacrifice Teal'c, but one leader stops them. Having seen the Prior destroy the village, Tomin sends Vala down, where she sees if Carter had managed, just in time, to get the device working...

13The Road Not Taken

After an experiment to increase the range of Merlin's device goes terribly wrong, Sam has an accident which transports her to a parallel universe, where SG-1 has a very different composition, since history was changed by a failed attack by one Ori ship... and a whole fleet is expected soon. She insists upon abandoning the -killed- parallel Carter's line of work and pursues hiding the entire parallel Earth. It works! Even when the Ori fire at their position, nobody is hurt. The parallel Hank Landry is President, and three years prior had imposed permanent Martial Law. The more Carter learns about the perversion of civil liberties, the more she shifts her efforts, even when rewarded by a post as Presidential Defense Adviser, to restoring them, but thus incurs the active wrath of those in power who are eager to remain so. Time to get back, but how?

14The Shroud

Daniel Jackson, who was left behind fighting off Adria while the other SG1-members escaped trough the Stargate, is found working as a Prior: the best in the business, who doesn't need to use any threats to talk people into conversion to Origin. Hoping there is still some of his personality left, the team (plus General Jack O'Neill) kidnaps him. Daniel explains how he temporarily has Merlin's personality and knowledge in himself, and had deliberately allowed Adria to turn him into a Prior, while delaying to finish Merlin's weapon she'd wanted, meanwhile hoping to get an Ori ship for Earth's side. But time is running out, since the team took unexpectedly long to capture him. Still, the generals, Carter, and Vala are most reluctant to go along with releasing him and opening the wormhole he needs to bring the weapon through. Even the White House wants to kill him, or at best, keep him in stasis until he is reverted to his human nature by Merlin's genetic manipulation. But then his plan is wasted- unless the others can be trained to do it in his place (so only they are at risk, not the entire galaxy in case Daniel is Adria's Trojan Horse). After giving them the necessary information, Daniel suddenly frees himself while Richard Woolsey is with him and takes control of a space ship after beaming up Jack too, just after the others have undertaken their mission to Adria's lair, where Daniel, about to be genetically reverted, arrives just in time to tip the balance in favor of...

15Bounty

SG-1 blows up three transport ships in a row; Netan puts a price on their heads. General Landry grants the team members spare time on Earth. Daniel spends it researching in a library, where he meets a bounty hunter who tries to seduce him, then switches to her handgun... but is taken out by a bus. Sam gives a lecture on Air Force technological progress together with Dr. Bill Lee; a sniper nearly misses, but is taken out with an experimental weapon they'd brought along to demonstrate. Teal'c is injured by surprise at a Jaffa camp and successfully traps the killer to try again. Cam goes to his Kansas high school reunion and Vala succeeds in making him bring her along, pretending to be his accountant and partner. His still sexy former flame he'd believed out of his reach, Amy Vandenberg, is initially scared off by Vala, but, divorced and interested, explains she still has a secret crush on him. Alien bounty hunter Odai Ventrell assumes numerous classmates' appearances to kill him. Vala's failed rescue gets them both captured publicly, so he threatens to kill off reunion guests unless the other SG-1 members take their place, but they trick him using Chimera technology; they hope Netan's failure to eliminate them will rekindle the power struggle and Odai reacts surprisingly.

16Bad Guys

When SG-1, minus Carter, investigates a previously unexplored planet expecting to find themselves in a pyramid, they are astounded to find themselves in a museum. Finding a party occurring in the lobby, they decide to leave and make first contact later, but they find that the DHD is a replica and thus incapable of getting them home. They are discovered and believed to be rebels and are forced to take hostages to buy time for their escape.

17Talion

Teal'c and Bra'tac are among the numerous victims -though only wounded- of several bomb attacks killing 32 men at a summit in the Jaffa settlement Dar Eshkalon. As soon as physically able, he swears to avenge them personally, suspecting the honor-less, ambitious warrior Arkad; General Landry refuses to sanction a killing mission without solid proof, but cannot stop Teal'c going it alone. Bra'tac explains to Daniel Arkad's sinister past, probably even murdering Teal'c mother. Information from resistance on another planet indicates Arkad is in league with the Ori and a plan to attack Earth. Arkad comes meet General Landry, offering to help defend Earth against the Ori, denying any part in the bombings, while defending Origin, incriminating a Jaffa sect. SG-1 is now ordered to find and stop at all cost Teal'c, who is using torture. But Teal'c, committed to killing Arkad, reaches his place, but is wounded, captured, and made to duel Arkad after it is confirmed he had killed Teal'c's parents.

18Family Ties

Stargate's HQ gets a video message from Vala's most unreliable father Jacek on the planet Robak- he claims to know about the late Arkad's plans to attack and blow up Earth, even about the several cloaked, naquadah-laden cargo ships in orbit, and offers details in exchange for sanctuary. General Landry asks Dr. Lam to help him resume contact with her mother Kim, his ex. Even after the cargoes are found and blown up, Vala abhors her dad's entry. The general asks her to go easy on him, realizing that he, too, neglected his daughter because of his career, even if Jacek's neglect was just criminal. When Cam and Daniel go tell Jacek he shouldn't scam people, he tricks them into talking to Vala for him. Vala goes over just for catharsis, telling him she's through picking up the pieces of his tricks, and he certainly keeps scamming- as Daniel also finds even with Terak, a Jaffa from an escaped cargo ship, who hopes to sell the naquadah. When they are apprehended, Jacek promises to help track it and override the rigging of the cargo ship. The Jaffa wait for Jacek and Vala, intending to eliminate them now that Terak is gone, but SG-1 saves them. Since there never was an override, he cheerfully flies away alone in the cargo ship, ignoring that his treachery was anticipated, it's a decoy...

19Dominion

Vala gambles, wins a cargo ship, but is found cheating; then Adria appears, throws everyone out and claims she has a new Ori fleet and an operational intergalactic Stargate. Vala tells her scary daughter how she helped Daniel, after a dream, reading the mysterious clava thessara-symbol's mystery, which led to a single planet address, where Athena's treasure house must be; after a disastrous visit there, the team refused to follow the next interpretation, fearing it's just a trap set up by Adria, so Vala is declared a security risk, grounded and confined to Area 51, but escapes through the Stargate. Adria takes her along as she hears the team still plans to visit the address, by starship. Upon arrival, they are trapped by SG-1, which however finds itself surrounded by lord Ba'al's troops. Ba'al uses the rings to beam up Adria into an electromagnetic cage in his starship. Back on Earth, General Landry worries what damage the two might do together and wants Adria back. Daniel and Sam now show Vala she has been implanted by Galaran technology with fake recollections of her entire adventure 'til the meeting with Adria. Even though she claims that's impossible, Ba'al is confident he can take control over Adria's loyal Ori troops through her- by implanting a symbiote. The team finds Ba'al's Jaffa and clones killed by symbiote poison, except one Jaffa who secretly used tretonin. The team ring-beams from the cloaked Odyssey starship into Ba'al's, shoots him and captures Adria, but back on Earth, she is found to be under the control of his symbiote. Instead of just killing the evil double, they contact the Tok'ra which send Ta'Seem to extract the symbiote and replace it with a Tok'ra one, but Ba'al manages to poison Adria, who has to be put down. Suddenly Adria wakes up, uses mind-power barricading herself in the sick bay with Vala, tells them she needs time to prepare for ascension, as Daniel guesses outside, and succeeds before the team can cut their way in by blow torch. Nobody knows what this will mean for the future, especially as it remains uncertain whether the Ori are still alive. If not, she may have gained all their former powers, and at least one clone of Ba'al still remains...

20Unending

General Landry accompanies SG-1 on a mission to collect the knowledge of the Asgard. When the Ori show up however, Sam is forced to evacuate the crew and Landry and SG-1 stay aboard, but are stuck helpless in a time dilation field for decades.
