After SG-1 receives a rather cool reception from General Hammond upon returning to the SGC from their latest mission, they’re sent into quarantine and hear about a chemical spill affecting the entire Cheyenne Mountain complex. In the infirmary, all four are drugged, though it wears off early for Teal’c because of his Goa’uld symbiont. Teal’c discovers that an alien species has taken over the SGC, and quickly escapes from his guards, also rescuing Carter. Teal’c stays behind to fight and rescue Daniel and O’Neill while Carter escapes, but he is soon overcome. Once outside, Carter contacts Maybourne, one of the SGC’s most hated enemies, to inform him of a foothold situation and requests a meeting in a public place – but at that meeting, Maybourne hands her over to O’Neill and Daniel to be taken back to the SGC. Maybourne promises to accompany her as well. But it’s only on the return flight to the SGC that either Carter or Maybourne realizes that the alien incursion may have already spread as far as the Pentagon.
