Plot Outline:
When General Hammond announces he is stepping down as head of the SGC, O'Neill suspects that there is more to his decision than he is letting on. And, as it turns out, O'Neill is right as he discovers that the NID was behind the change of command. Fed up with the general's inability to acquire alien technology through whatever means necessary, it pressured him into resigning. When Hammond's replacement breaks up SG-1 and assigns Carter the task of building a planet-killing Naquadah bomb, O'Neill takes matters into his own hands. He decides to take on the NID, but his success will rest in the hands of a most unlikely ally: Colonel Maybourne.
