Not a bad episode, though a little bland compared to the rest of the show.
Carter and Jacob are at the Alpha site trying to modify a weapon to use against Anubis' 'supersoldiers' when they are attacked.
The Alpha site is quickly overrun, and Carter and Jacob run for the hills, all the while being persued by one of the aforementioned 'supersoldiers'.
When the SGC hears of this, O'Neill takes it pretty hard and eventually goes off to try and find Carter.
Season 7 seems to be Carter's season. A large percentage of the episodes focus mostly on her, and this is no exception. managing to outmanoevre her enemy, she stays alive until finally O'Neill can come to the rescue.
