The irrepressible Stargate team faces their biggest challenge yet as they set out in search of the ancient artifact with the power to defeat the villainous Ori before they launch a devastating attack on planet Earth. The Ori are determined to exterminate all traces of mankind, but not if Daniel Jackson (Michael Shanks), Teals (Christopher Judge), Vala (Claudia Black), Sam (Amanda Tapping), and Cam (Ben Browder) have anything to say about it. With a scheming I.O. operative aboard the Odyssey, the final fight for humanity begins to unfold in the deepest reaches of outer space. Beau Bridges co-stars.
