While on an evacuation mission, a symbiote takes Captain Samantha Carter as its host and makes its way to Earth in order to leave for another planet. However, the rest of the team finds out and arrests her. She tells the team that she is a member of the legendary Tok'ra and that an Ashrak (Goa'uld assassin) is sent to kill her.
As SG-1 helps a group of people on the planet Nasya flee through the Stargate from a Goa'uld attack on their world, Captain Samantha Carter stops to give CPR to Quinta, a fallen villager. He suddenly grabs her head, and something enters her. Blood on her lip, Carter's eyes glow. She has been possessed by a Goa'uld symbiote.
Carter returns through the gate and tries to act as normal as possible, though through the mission debriefing her comrades notice something is different about her. Dr. Janet Fraiser invites her to come check on the Nasyans, many of whom have been moved to the hospital at the nearby Air Force Academy. Finally, she goes to visit Cassandra Fraiser, and the young girl senses that Carter has been taken by a Goa'uld. She locks herself into Dr. Fraiser's office and demands to see Colonel Jack O'Neill.
Cassandra convinces O'Neill that Carter was infected, and he takes action. When he injects Carter with a serum that "would bring down an elephant", the Goa'uld inside her becomes active and demands the Stargate be activated. Carter is apprehended and put behind bars at Stargate Command. The Goa'uld reveals itself to be Jolinar of Malkshur, and demands release. The parasite even promises to return Carter to them, fully restored to who she was. O'Neill does not budge. Suddenly, Carter's personality emerges and begs O'Neill to believe Jolinar but he takes it as a Goa'uld trick.
Finally, Jolinar reveals that she is a member of the Tok'ra, a group of rebel Goa'uld who oppose the System Lords and seek power for good. They are the most hated enemies of the System Lords, who constantly chase down any leads in an attempt to infiltrate and destroy them. She also explains that the System Lords will not allow the Tau'ri to thrive and become a threat. Already a far more powerful attack is being planned. Teal'c, at least, is convinced. Jolinar talks with Dr. Daniel Jackson and tells him she knows where Sha're is.
When the Ashrak finally locates his victim, Jolinar, Carter suffers torture and almost death at his hands. The hunter is found, and Teal'c finally kills him with two shots from a Zat'nik'tel, also stunning Daniel in the process. Meanwhile, Carter is fighting for her life in the infirmary. When she recovers, she tells O'Neill that Jolinar has given its life to save hers.

O'Neill: Janet says you've been a little upset since Sam was here. What happened?
Cassandra: She said she'd kill me if I told.
O'Neill: You don't mean "kill you" kill you? Oh, I doubt that.
Cassandra: She said she would.
O'Neill: Cass, Sam loves you. She'd never do anything to hurt you.
Cassandra: She would now.
Cassandra: She's a Goa'uld.
Teal'c: Are you injured?
Jackson: Dumb question. But thank you. I think.
Teal'c: You are welcome.
Jackson: Just don't ever do that again.
Teal'c: Assault the Goa'uld's ego. Make him appear foolish. He may then reveal things simply to make himself appear more powerful.
O'Neill: Ah, come on Teal'c. They're smarter than that.
Teal'c: I have seen many Goa'uld strategies revealed and certain victories lost, simply because of Goa'uld arrogance. It is the Goa'uld's greatest weakness.
Carter: Not all Goa'uld are the same. There are a few that oppose the System Lords and their ways. You must have heard of the Tok'ra.
Teal'c: Every Goa'uld seeks power for his own reason and would betray his own brother to achieve it.
Carter: Some seek power for a greater purpose. Not every Goa'uld is an enemy to the people of this planet. The Tok'ra are real. No matter what Apophis has told you.
Teal'c: I have yet to meet one.
Carter: You have now. I am Jolinar of Malkshur.
Teal'c: There is an old legend among the Jaffa, forbidden to speak of, concerning a group of Goa'uld who oppose the ways of the System Lords. This group is called the Tok'ra. This Goa'uld, Jolinar of Malkshur, claims to be part of that group.
O'Neill: Can you be sure he is who he says he is?
Teal'c: I cannot.
Carter: Unfortunately, we do not carry identification.
O'Neill: Okay, let's try to build a little trust here, shall we? One of the Nasyans we brought back was very badly burned. But somehow he just got up out of his hospital bed and disappeared. Who is he?
Carter: It must be the Ashrak.
(O'Neill looks to Teal'c for translation.)
Teal'c: It means hunter.
O'Neill: A Goa'uld?
Carter: Yes. An assassin of the highest rank who carries out the orders of the System Lords.
O'Neill: Who's he here to kill?
