04.05 Episode #71
Airdate: July 28, 2000

SG-1 and SG-14 are on Vorash preparing to sign a treaty of alliance between Earth and the Tok'ra, when Major Graham, of SG-14, suddenly begins firing a weapon uncontrollably before taking his own life. Anise determines that Graham was a zatarc, a victim of a new kind of Goa'uld mind control technology. Zatarcs are programmed as suicide assassins, and their programming is covered by false memories. Only new and unproven Tok'ra technology is able to detect zatarc programming, of which even the victim is unaware, and Anise brings the device to Earth to test members of the SGC.

Anise begins her testing procedure, and Lt. Astor, another member of SG-14, is also identified as a zatarc. However, an attempt to reverse her programming causes her to lose control and take her own life. More troubling still, the device determines that both O'Neill and Carter may also be victims. With the signing of the treaty imminent, O'Neill and Carter are faced with the choice of indefinite sedation and confinement as possible security threats, or submitting to the same risky deprogramming technique that led to Astor's death. O'Neill agrees to the experimental procedure.

As O'Neill prepares for the dangerous deprogramming, Carter realizes the flaw in the zatarc technology. The device can misread emotions, interpreting omissions as lies, and giving a false reading. O'Neill and Carter are retested, admitting feelings they had previously concealed, and they are cleared as zatarcs. It is not until the real zatarc attempts to assassinate the Earth and Tok'ra leaders that his identity is discovered. It was Martouf who was the unknowing victim of zatarc programming, and who dies as he attempts to carry out his suicide mission.
