O'Neill and the SG-1 team are on a mission to Nasya, hoping to rescue the survivors of a planet that has been attacked by the Goa'uld. During the rescue, however, Dr. Samantha Carter's (Amanda Tapping) body is taken over by a Goa'uld that was hiding in the body of a mortally injured Nasyan. Her fellow team members don't notice the change, but when the team returns to Earth, Carter's young friend Cassandra (Katie Stuart) recognizes the Goa'uld immediately. Cassandra tells O'Neill that Carter is confined to a cell and O'Neill bargains with the Goa'uld for Carter's life. The Goa'uld tells Teal'c that he is Jolinar of Malkshur, one of the Tok-ra Goa'ulds, a rebel group opposed to the bloodthirsty ways of the system lord. But he also reveals that he has been followed here by Ashrak, an assassin trained in the ways of the Goa'uld. Unless the SG-1 team can stop him, Ashrak will kill Jolinar, taking Carter's life as well.
While exploring a seemingly insignificant planet, O'Neill and the SG-1 team are approaced by a ragged figure who pleads for their help from a pursuer named Taldor. They try to defend him, only to discover that the man ia fleeing murderer. Taldor means Justice and, by aiding the man, the SG-1 team becomes complicit in his crime. Over their protestations of innocence, the team is sent through a Stargate to Hadante, a penal world where brute strength and raw power rule. Strangely, the most powerful person on Hadante seems to be Linea (Bonnie Bartlett), a diminutive woman who strikes fear into brutes such as Vindoor with her mysterious powers. SG-1 strikes a deal with Linea: if she will help power the Stargate using her cold fusion power source, they will help her escape with them. It seems a fair trade, but there's more to Linea than meets the eye.
O'Neill and the SG-1 team travel to P7J989, where they discover a beautiful garden and a dome full of strange metallic chambers, each containing an unconscious person. As the team inspects the chambers, they are trapped and knocked unconscious. They awaken to find they are reliving pivotal moments in their lives in the hope of changing the outcome. Teal'c joins O'Neill on a battlefield where the Colonel lost a patrol; Daniel and Carter witness the death of his parents in a freak accident. A shadowy figure called The Keeper (Dwight Schultz) steps forward and explains that they are part of a game that feeds memories into a virtual reality he has created for the amusement and edification of 'his residents' in the metallic chambers. He explains that they are there because, he says, the planet has been rendered uninhabitable because of the pollution on the planet. But, The Keeper is lying when the SG-1 team threatens to reveal his deceit to the others, he admits defeat. Or does he?
While exploring planet P3R 636, O'Neill and the SG-1 team come across what appears to be a troop of Jaffa warriors and ceremonial priests delivering Naquadah, an element treasured by the Goa'uld, through the Stargate. What catches Daniel Jackson's eye, however, is the beautiful Princess Shyla, the meloncholy daughter of the planet's ruler, Pyrus the Godslayer. When she attempts suicide, Daniel saves her life, but in doing so, he and the rest of the team are captured and forced to work in the Naqadah mines. When Daniel is injured in an escape attempt, the princess brings him to the palace and nurses him back to health, using a Goa'uld sarcophagus. As O'Neill and the rest of the team work as slaves in the mine, Daniel attempts to negotiate their release. Princess Shyla explains to Daniel the secrets of the planet. She reveals how her father drove out the Goa'uld ruler, and now rules the planet with an iron hand, sending Naquadah through the gate in hopes of appeasing the Goa'uld. She explains the while Pyrus has lived for 700 years, thanks to the rejuvenative powers of the sarcophagus, he is now dying and she will succeed him. She wants Daniel as her King, and she's willing to use the power of the sarcophagus to convince him to accept the thrown.
O'Neill and the SG-1 team return to Cimmeria after learning that the Goa'uld have invaded the planet. The team feels responsible since, on their previous visit, they destroyed "Thor's Hammer", the planet's main instrument of defense agains the Goa'uld. The team makes some remarkable discoveries ont he planet. Samantha Carter discovers that she has the power to use the Goa'uld ribbon device. It soon becomes clear that the SG-1 team need help to fight the massive enemy force lead by the vicious Goa'uld Heru-ur. Teal'c, O'Neill and Olaf head to scout the Goa'uld encampment and soon find themselves face to face with the enemy. Meanwhile, Daniel Jackson, Samantha Carter and Gairwyn search the Hall of Thor's Might, where they believe they might find weapons to defeat the Goa'uld. They find the hall, where they are presented with a series of tests by a hologram of Thor, the Asgard god who guards the planet. Can they pass the tests and find a way to defend the planet? And can they do it before Heru-ur's army wipes out the rest of the Cimmerians and the rest of the SG-1 team?
While exploring a now-dead planet, O'Neill and the SG-1 team find an orb that sends out electromagnetic signals. They think it is a time capsule of some sort and are intrigued by its power source, which seems to have lasted a millenia, they bring it back through the Stargate. When Samantha Carter and Daniel Jackson begin their tests, however, the object begins to heat up and the team decides to send it back through the Stargate. The object, however, seems to have other plans. While it is brought to the Stargate, it shoots bolts through the concrete walls, floor and ceiling of the facility, including one that pierces O'Neill's shoulder. Further investigation reveals that the object is sending out alien organism that is infecting people, computers and the building itself. Attempts to destroy the orb only make it grow faster. As the computer screens go dark and the facilities self-destruct mechanism begins its countdown, Carter suggests they let the organism take over O'Neill's body in the hop the orb will use him to communicate with them.
Teal'c's mentor, Bra'tac arrives unexpectedly through the Stargate with shocking news: the Goa'uld Apophis survived the destruction of his ship and has now kidnapped Teal'c's son, Rya'c. O'Neill and the rest of the SG-1 team agree to join Teal'c as he returns to Chulak to rescue Rya'c, but when they arrive they find much has changed. Because Teal'c didn't return from Earth, his wife, Drey'auc assumed he was dead and married his old friend, Fro'tak. To make matters worse, Ray'c has been brainwashed by Apophis which causes him to denounce his father as a traitor and foil the team's attempts to rescue him. Fro'tak becomes jealous after seeing Teal'c and Drey'auc rekindle their marital flame. The team is almost caputred and Fro'tak attempts to betray them to Apophis, forcing O'Neill to take drastic action. But, Teal'c sees a glimmer of hope when Rya'c slips a hidden message into his denunciation of his father. Teal'c wants to rescue him and take him back to Earth and although O'Neill agrees, he suspects Rya'c - or his controller, Apophis - may be setting an elaborate and deadly trap.
Daniel Jackson and Teal'c travel back to Abydos, as it has been a year since Daniel left to fulfill a promise he made to Sha're's father, Kasuf. When they arrive, Daniel learns that his wife, whom he hasn't seen since she was taken by the Goa'uld, is nine months pregnant. The father is Apophis, who plans to use the baby as his new host. O'Neill and Carter are in Washington to receive a medal for their bravery and receive their own shocking news. O'Neill is approached by a reporter named Armin Selig who says he has the inside scoop on the Stargate program and is going to run the story. Carter is reunited with her father, who tells her he has cancer. As Carter and O'Neill deal with these large issues, Daniel and Teal'c try to find a way to get Sha're back to Earth before the child is born, and the sleeping Goa'uld within her awakens. When the arrival of a ship carrying Apophis' enemy Heru-ur prevents them from returning through the Stargate, Tea'lc devises a plan to use the rivalry between Apophis and Heru-ur to help them escape.
While exploring BP6-3Q1, O'Neill and the SG-1 team are attacked by giant insects. The team escapes through the Stargate but not before Teal'c is stung. When Teal'c returns to Earth, a strange transformation begins, as the insect virus transforms Teal'c's DNA into something like its own. The change baffles Dr. Samantha Carter and geneticist Dr. Richard Harlow and it terrifies Teal'c, who makes O'Neill promis he'll stop the transformation. But Tea'lc's condition intrigures Colonel Maybourne who sees the potential for biological weapons in the insect venom. Maybourne uses his presidential mandate to take custody of TEal'c but the Jaffa escapes while being translaterd, leaving behind his Goa'uld larvae. As Teal'c hides out on the mean streets of the city, he is befriended by Ally, a young homeless girl, Oneill and the team return to BP6-3Q1 to capture the insect. While there, they discover the terrible power of the insects: how they bypass normal breeding by genetically transforming their victims into their offspring. With time being of the essence, the Stargate Command must devise a vaccine and keep the larval Goa'uld alive. Most important of all - they must find Teal'c boefore Maybourne does.
Samantha Carter has a vivid dream: she sees through the eyes of Jolinar, the Tok'ra or rebel Gou'ald, who briefly inhabited her body before dying. Although her father Jacob is dying of cancer, Carter knows she must go on the mission with O'Neill and the rest of the SG-1 team to find the Tok'ra on planet P34-353J. Upon their arrival they meet a suspicious and heavily armed group of Tok'ra, but as Carter reveals her knowledge, relations begin to warm up. The team learns more about the Tok'ra - how they ususally only inhabit willing hosts and do not use the Goa'uld sarcophagus - and Carter learns more about the relationship between Martouf and Jolinar, who were partners for nearly 100 years. There is even talk of an alliance, but the trust is fragile and the outcome of the negotiations are uncertain.
The Tok'ra have turned down SG-1's request for an alliance against the Goa'uld because, as Garshaw explains, the earthlings don't offer enough rewards to justify a security breech. And the fact that none of the humans will act as host for Selmak, a Tok'ra whose host is dying does little to build trust. However, Samantha Carter has an idea. Her father, Gen. Jacob Carter is dying of cancer. If he will become a host, it will save both his life and that of Selmak. But when she and O'Neill return to the Stargate to propose the idea to her father, the Goa'uld, tipped off by a spy, launch an attack on the Tok'ra. The Tok'ra have enough warning to relocate, but by the time O'Neill, Carther and her father return, the attack is underway. The bonding of two beings as sick as Gen. Carter and Selmak would be difficult under the best of circumstances. With Goa'uld death gliders filling the sky, it requires even greater risk and urgency.
The SG-11 team has not returned from its mission to planet PXY-887, where they recently discovered an element, Trinium, that is a hundred times lighter and stronger than steel. Instead, the inhabitants of the planet have fired an arrow made of Trinium through the Stargate and into the shoulder of Jack O'Neill. With O'Neill in the infirmary, the SG-1 team, led by Samantha Carter, heads through the Stargate to investigate and to negotiate a mining treaty with the inhabitants. SG-1 is knocked out on the arrival and when they awake, they meet Tonané, a plains spoken Coast Salish Indian, who explains that the SG-11 team were taken by 'the spirits' - the same spirits who gave the valuable metal to his people. Carter and the others are skeptical as they address T'akya, the wolf, and Xe'ls, the raven, even after the SG-11 team mysteriously reappears. Negotiations with the Salish reach a stalemate and Tonané returns to Earth with SG-1 and SG-11 to look at alternative mining methods. But when Gen. Hammond tells Conner news of plans by N.I.D. to mine the planet whether the Indians agree or not, strange things begin to happen as the spirits, determined to protect the Salish, reveal their true nature.
When a group posing as the SG-1 team steals the climate-controlling Touchstone from the planet Madrona, the planet's weather deteriorates, threatening inhabitants with imminent death unless the stone is recovered. Madrona's high priest Roham and his granddaughter Princess La-Moor, blame the SG-1 team for the theft. The SG-1 team make a disturbing discovery: the secon Stargate on Earth, which had been officially decommissioned, was reactivated by high level orders and used to steal the Touchstone. Now the weather device is on Earth and being used to manipulate the world's climate. When Gen. Hammond discovers the whereabouts of the second Stargate, the SG-1 team races to it, determined to find the Touchstone before all of Madrona perishes, and to discover the hidden agenday behind the Touchstone's theft.
Daniel and the rest of the SG-1 team travel to an ancient room that houses alien inscriptions in an attempt to decode alien languages discovered by a probe. When O'Neill peers through a viewer in the ancient room, he is caught momentarily in its grasp and shortly after alien words begin appearing in his speech. Before long, his entire brain is taken up with a superior knowledge virtuallly indecipherable to the rest of the team. Daniel is certain that O'Neill now possesses the knowledge of the Ancients, the alien race who invented the Stargates, but he realizes the knowledge is too complex for human minds and will likely cause O'Neill to lose his mind. In an attempt to save himself, O'Neill must access his subconscious mind to discover ones with a greater knowledge than his own, ones who may also have important knowledge about the destiny of mankind.
While attempting to save the members of SG-10 from a black hole on planet P3X-451, the SG-1 team activates the Stargate and exposes themselves to the hole's gravitational pull. Trying to break free, the team shuts down the gate's power and in the ensuing explosions, Teal'c and Daniel are badly injured. Even without power, the black hole's gravity continues to draw the SGC closer to the swirling wormhole. With the intense gravity field warping the space/time continuum, the SGC loses contact with the outside world and the Pentagon sends O'Neill's former mate Col. Cromwell to investigate. Cromwell is tormented with guilt for deserting O'Neill during a Soviet mission and volunteers to partner him in the attempt to save the SGC. Time slows to a near stand-still inside the SGC, where only O'Neill and Cromwell are left. Carter scrambles for a solution before the SCG and then the Earth are torn apart by the black hole's gravitational tides.
When the SG-1 team stumble upon the chamber of former Goa'uld enemy Ma'chello, they fall victim to his powerful body swapping invention. Ma'chello takes on Daniel's body and the young archeologist finds himself trapped in the body of an old and dying man. In Daniel's body, Ma'chello flees the SGC and gets a taste of life on Earth for the first time, while Daniel lies on his death bed in the hospital. In an attempt to help their friend, O'Neill and Teal'c bring the invention to the SGC, but accidentally trigger it and find themselves in each other's body. When Ma'chello is tracked down and returned to the SGC, he reveals that the machine's process is irreversible.
Pursued by Goa'uld death rays, former Goa'uld conqueror and sworn enemy of SG-1, Apophis throws himself at the mercy of the team and despite his past evil, they grant him sanctuary. Apophis, who shows signs of torture, is slowly dying and promises all the knowledge of the Goa'uld in return for a new host body. When O'Neill rejects his offer, Apophis reveals that he is pursued by an ancient and powerful Goa'uld named Sokar, the original god of death. Conquered by Apophis in Egyptian times, Sokar has come to wreak his revenge and will kill anything that stands between him and his ancient adversary. The team's Tok'ra ally Martouf tells SG-1 that unless Apophis is sent back to face his fate, all those around him will be destroyed, either by Sokar or the many Goa'uld who wish their former leader dead.
During a routine reconnaissance mission, the UAV plane crashes into a cactus-like plant on a planet inhabited by an unusual life form. Sent to recover the plane, the team discovers those living on the planet are friendly, gentle and far simpler than their human counterparts. Shortly after the team's arrival, aliens begin falling ill and before long a plague of illness sweeps the race. O'Neill and Daniel begin acting erratically and complain of headaches which disappear once they are back at the SGC. As the number of afflicted aliens grows, it appears that the SG-1 team has unwittingly unleashed something that threatened the survival of this civilization.
A young boy (Jeff Gulka) gains entry to the SGC and tells the SG-1 team he has come with his mother, a member of the invisible Reetou race. The boy, who asks to be called Charlie after O'Neill's dead son, announces that the Goa'uld destroyed his planet Reetalia and now Reetous rebels intend to kill all human beings. The rebels believe that by killing all potential hosts for the Goa'uld they will gradually eliminate the the Goa'uld themselves. His mother created Charlie to serve ans an intermediary between the Reetou and humans and to warn them of the coming rebel attack, but due to his accelerated growth, the boy's organs are now failing and unless he receives expert medical help he will die soon. The SG-1 team call Carter's father Jacob (Carmen Argenziano), a Tok'ra, to help them. He brings a laser device which can make the Reetou visible and destroy them. But, it may be too late. Thousands of Reetou are swarming outside the wormhole and an unknown number may have already gained entry into the SGC.
Through a solar flare, the SG-1 team are propelled back in time to 1969, landing in a top military facility. Carrying a letter General Hammond gave her, Carter (Amanda Tapping) is searched by a young Lieutenant (Aaron Pearl) who is astonished by the letter's contents. As the team is transported for further interrogations, the Lieutenant helps them escape and tells them the letter appeared to be from him many years in the future. Desperate to find the Stargate so they can return to the present, the team seeks out Catherine, who they believe may know its location. Hitchhiking to see her in New York, they are picked up by Michael (Alex Zahara) and Jenny (Amber Rothwell), two friendly flower children on their way to Woodstock. They immediately warm to the team's fugitive appearance. Carter discovers that Hammond's note includes the date of the next solar flare and they race to the Stargate before their chance of leaving the past is lost for good.
Awakening from what seems like cryogenic suspension, O'Neill finds himself in a futuristic version of the SGC surrounded by unfamiliar faces. He is told by doctors he has been frozen for 79 years and the rest of the SG-1 team perished long ago. The doctors hook O'Neill to a device which turns his memories into holographs then question him for information about races able to defeat the Goa'uld. The doctors claim they need all the help they can get in their current war against the Goa'ulds. When O'Neill overhears the doctors speaking in Goa'uld voices, he realizes he maybe part of an elaborate set up. He escapes and discovers the SGC is actually a replica built inside a Goa'uld stronghold, and that in nearby rooms Daniel and Carter are undergoing similar treatments. Attempting to escape, the three are blocked by Hathor who, enraged by their refusal, prepares to implant one of them with a larvae.
