When an SG team returns with a corn-like food stalk that has addictive, and mind altering effects, SG-1 is sent to investigate. They head to the planet where the corn-like food, known as kassa, is grown, but their investigation provokes an angry response from the Lucian Alliance that controls the food. While under fire from the alliance, and as they are attempting to dial home, the Stargate and DHD suddenly disappear, leaving SG-1 trapped. After SG-1 is later rescued from the alliance by Earth's newest ship, the Odyssey, SG-1 tries to find out who stole the gate. Gen. Landry decides to seek help from the Goa'uld Nerus. Nerus eventually breaks down, after some creative torture techniques by Gen. Landry, and tells them who stole the gate on the alliance's planet and several other gates as well. The answer shocks the team, and poses many additional impossible challenges to getting the gates back, but reinforces the need that they do, for the sake of Earth's future existence.

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.
