About the title
While the SG-1 team tries to destroy Ba'al, the last of the Goa'uld lords, Teal'c and Vala mysteriously disappear. Carter, Daniel, and Mitchell realize that the time continuum has been disrupted and the Stargate program has been erased from history. The heroes try to get their difficult message across to the authorities, but Goa'uld cruisers arrive in orbit, led by Ba'al, Queen Qetesh, and Prime Minister Teal'c. The SG-1 team must find the Stargate and restore the proper course of events before the world is enslaved by the invaders.
