What "Stargate SG-1" 13-th episode about
After a poor training simulation with new potential recruits for the SGC, O'Neill tries one more exercise, which goes equally bad for the recruits. At the end of the exercise, Jack receives a cryptic call and repeats into the phone the word 'Foothold.' The recruits hearing this know that a potential alien takeover of the SGC has occurred. Jack is then shot, as he shoots and hugs several unknown strangers that arrive in vehicles to talk to Jack. The recruits now appear to be the only people around that can help O'Neill in this situation. They sneak into the SGC through the ventilation system, and try to find Carter, who had warned O'Neill and has the answer to what is happening. However, all is not all what it seems there. And in the end, the recruit team leader, Lt. Elliott, must risk passing to save one of his teammates.
