Synopsis by Hal Erickson
In this followup to the previous episode "Double Jeopardy", the SG-1 evacuates the Tok'ra from their home planet Vorash to a new, secret location. Alas, their whereabouts is revealed to the Gou'ald Apophis (Peter Williams) by the treacherous Tanith (Peter Wingfield). With the Goa'ulds bearing down upon them, the SG-1 team hatches a desperate plan--one that could well set off an apocalyptic chain reaction. The final episode of Stargate SG-1's fourth season, this episode establishes a "cliffhanger" that would not be resolved until the beginning of Season Five.
