Cameron Mitchell, a former fighter pilot who flew an F-302 in the battle over Antarctica is appointed, just to realize the original team has dispersed with members following their own paths: Teal'c to manage the Jaffa Nation, Carter to Area 51 for alien R&D, and Dr. Jackson to Atlantis as an Ancient expert. Mitchell then finds that an artifact which could unravel an ancient treasure is his only chance to restore the team.
