SG-1 searches for an ancient weapon which could help them defeat the Ori, and discover it may be in the Ori's own home galaxy. As the Ori prepare to send ships through to the Milky Way to attack Earth, on board the Odyssey, SG-1 travels to the Ori galaxy. The International Oversight Committee has their own plans and SG-1 finds themselves in a distant galaxy fighting two powerful enemies.

Noranti and Sikozu are recent additions to the crew. A shocking former enemy will play a major role as well. The stakes have risen for the crew and for the universe itself, including escalating dangers that threaten not only the Farscape galaxy, but Crichton's home galaxy as well.

Stargate is an intergalactic gateway, developed by an ancient civilization, that links planets from other solar systems to ours. The U.S. Air Force assembles a Stargate team headed by Colonel Jack O'Neill for interstellar peacekeeping missions. (All 21 episodes from the first season are presented here. DVD format.)
