This thrilling feature-length film picks up where "Stargate SG-1," left off, thrusting the Stargate team -- Daniel Jackson (Michael Shanks), Vala (Claudia Black), Teal'c (Christopher Judge), Sam (Amanda Tapping) and Cam (Ben Browder) -- into their most exciting adventure yet. In search of an Ancient artifact they hope can defeat the oppressive Ori, the team learns that the Ori are set to launch a final assault on Earth and a double-crossing I.O. operative is aboard the Odyssey!
