While inspecting a mysterious weapon on a distant planet, Carter is inexplicably knocked unconscious. She is taken back to the SGC, leaving another team to investigate the aspects of the weapon. Carter finds that an ascended Ancient, Orlin, has followed her back to Earth. At first, she thinks he is imaginary, but then Orlin takes on a real human form to interact with her. He tells her testing the weapon will destroy the planet, and should not be tested. However, other forces now know of Orlin, and are watching Carter's every move. Things come to a head as Carter tries to stop the test firing of the weapon, and the secret governmental group's attempt to capture Orlin.

Step through the Stargate with SG-1, a team of soldiers and scientists, as they travel instantaneously to other planets to explore, forge alliances, defuse crises, establish trade, investigate ancient mysteries and defend Earth from such hostile forces as the Goa'uld and the Replicators.
For eight years, from their base at the U.S. Air Force's Stargate Command in the Rocky Mountains, Colonel Jack O'Neill, Dr. Daniel Jackson, Lt. Colonel Samantha Carter and alien warrior Teal'c have braved everything that the universe has thrown at them, from interstellar war and evil twins to passing and ascension.
But changes came to SG-1 as it began its ninth year of fearless service to Earth. New faces joined the team, as Lt. Col. Cameron Mitchell tries to fill the very big shoes of former SG-1 leader O'Neill, while General Hank Landry must adapt to the unique challenges of running Stargate Command, a posting unlike any other the military has to offer.
Offworld, SG-1 might have new friends - or new foes - in Vala, a former Goa'uld host turned freedom-fighter; and Gerak, a Jaffa leader who vies with Teal'c for political control of the new Jaffa nation.
