*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 Tak'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.
