Point of No Return

"Point of No Return" is the eleventh episode of the fourth season of Stargate SG-1.

Synopsis
Stargate Command is contacted by Martin Lloyd, who needs to speak to Colonel Jack O'Neill. SG-1 goes to Montana to see who he is, as he claims to be from outer space, and insists that a crashed spaceship is nearby. Meanwhile, more of his people wish to silence him.

Plot
Martin Lloyd, telephones Stargate Command and gets their attention by describing the Stargate and mentioning Colonel Jack O'Neill by name. He goes on to request a face-to-face meeting.

While O'Neill meets with the man, the rest of the team listens in. Martin explains that he is from outer space, and that he doesn't belong on Earth. O'Neill continues to stall him, even hunting through a local forest to find his spaceship, while Major Samantha Carter, Dr. Daniel Jackson and Teal'c (using his Murray for the first time) head to Martin's house to investigate further. There, what the team finds is of very little of use. He is a conspiracy theorist who catalogs everything. The main find, however, is a cabinet full of prescription drugs, and. As the team is searching Martin's house, a mysterious group of men observe them through cameras planted throughout.

Out in the woods, O'Neill and Martin have been unable to find anything and give up their search. O'Neill convinces Martin that he should stop taking his medications to help him remember more; he has a vision in which he see seven symbols; a Stargate address, with Earth as a point of origin. O'Neill now is convinced that there is more to Martin than meets the eye.

While this is going on, Jackson and Carter had gone to meet with Martin's psychiatrist, Dr. Peter Tanner. But he is nowhere to be found, his office is emptied out, and the "doctor" leads them into a trap. Jackson and Carter are captured and are interrogated by the four men watching them earlier.

As Martin continues skipping his medications, he remembers the location of his spaceship, and leads O'Neill to it. O'Neill calls in a team to analyze the ship; to get a better understanding of Martin's species. Martin further remembers that he had companions with him when he landed, fellow soldiers; his world was at war with powerful creatures that demanded Godlike worship; the Goa'uld.

They set a trap for the four men, by opening the ship's cockpit, and using Martin as bait. When they take Martin, O'Neill and Teal'c follow them to a warehouse where Jackson and Carter are being held. O'Neill and Teal'c free them, and find Martin tied up in the back of the van. As this happens, Martin's ship explodes, leaving a massive crater behind.

Martin now remembers everything; the five of them were soldiers, deserters that left their world behind and came to Earth to hide. Martin, learning of the existence of a Stargate on Earth, wanted to return home; but his compatriots overruled him and drugged him into amnesia. O'Neill takes Martin back to his home world only to find a smoldering ruin where a great city once stood.

Martin Lloyd: So you still don't believe me!? I'm an alien

O'Neill: (Sighs) You look pretty human to me.

Martin Lloyd: No. What I believe is that, thousands of years ago people were taken from Earth--maybe as part of some experiment, maybe as slaves, who knows. But the point is, there are entire civilizations up there, descended from those original humans.

O'Neill: Now that's just crazy talk.
