When an SG-team 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 Freya comes to the SGC with Martouf to try and test all SG-team 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?—Anonymous

While negotiating a treaty with the Tok'ra, Major Graham suddenly opens fire killing several of the Tok'ra and seriously wounding a member of their high council. Graham had become an agent of the Goa'uld who have essentially brainwashed him into becoming their assassin. With an upcoming summit between the Tok'ra leader and the U.S. President to sign an agreement, everyone at the SGC will have to be tested. O'Neill is dubious, especially when he sees that Anise is to be the tester. Her equipment reveals that both O'Neill and Maj. Carter have been programed by the Goa'uld but there is a far deeper reason behind it all.—garykmcd

During a negotiation with a Tok'ra leader, one SG member tries to kill him. Anise finds that the man has been brainwashed as an assassin by a Goa'uld technology called Za'tarc. The SG-1 is submitted to a test by Anise and the detector accuses that Jack and Sam might have been programmed as assassins. The alternative/cure is experimental may kill them or cause brain damage. What will they do?—Claudio Carvalho, Rio de Janeiro, Brazil

Supreme High Councillor Per'sus is on SGC to prepare a summit with the US president, helped by Daniel to phrase an alliance treaty draft, when SG Major Graham suddenly starts shooting, finally committing suicide. Disliked Tok'ra scientist Freya/Anise concludes he must be a Goa'uld-brainwashed "za'tarc", programmed as assassin, and convinces the general to submit all potentially exposed SG staff to her experimental test device. The first subject, Lieutenant Astor, looses control and commits suicide, but it's fixed and finds more za'tarcs, notably Jack and Sam, who are therefore confined during the summit, even planned to be sedated as the murder mission turning impossible may trigger suicide. Just before the injection, Sam realizes an emotional flaw in the test, while a tragic danger lurks.—KGF Vissers
