*Using exterior access, O'Neill and his young team enter the SGC and establish a base in Carter's lab. There they witness Teal'c and Daniel, both under alien influence, in control of the facility, and they discover a mysterious alien device in the briefing room that seems to be a power source. They devise a plan to eliminate the device and deactivate the gate, but as the team prepares to launch its attack to neutralize Teal'c and Daniel, it becomes apparent that Hammond and the SGC are monitoring their progress. The foothold situation is part of a new training scenario.
