A young boy gains entry to the SGC and tells the SG-1 team he has come with his mother, a member of the invisible Reetou race. The boy announces that the Goa'uld destroyed his planet Reetalia and now Reetou rebels intend to kill all human beings to prevent possible future hosts.

Awakening from cryogenic suspension, O'Neill finds himself in a futuristic version of the SGC. Doctors hook O'Neill to a device which turns his memories into holograms and then question him for information about races able to defeat the Goa'uld.
