Out of Mind (S02E22)

Awakening from what seems like cryogenic suspension, Col. Jack O'Neill finds himself in a futuristic version of Stargate Command, surrounded by unfamiliar faces. He is told by doctors that he has been frozen for 79 years and that the rest of the SG-1 team perished long ago. After hooking up O'Neill to a device that projects his memories as holograms, the doctors 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 them. When O'Neill overhears the doctors speaking in Goa'uld voices, he realizes that he might actually be the victim of an elaborate set-up. He escapes and discovers that SGC is actually a replica built inside a Goa'uld stronghold. In nearby rooms Dr. Daniel Jackson and Capt. Samantha Carter are undergoing similar treatments. O'Neill frees his friends, and together they make a run for it. Attempting to escape, the three are blocked by the beautiful but deadly Hathor, who, enraged by their refusal to cooperate with her interrogations, prepares to implant one of them with a Goa'uld symbiote....
