Margo goes on a solo mission to Berlin, delivering money to an agent in exchange for a list of names that the American Government may be interested in. Her contact is found dead and she is soon in the hands of the German police, being questioned for murder. The rest of the team head straight for Berlin to help her and get her out if need be.

A high level mole in the Pentagon has been passing on top secret info and compromising missions. They have also managed to place enough evidence to prove that it is Trout who is the mole. Trout comes out of hiding to ask Matt if he and the team could help clear him and find the real mole.

When they manage to capture a woman who could be the real mole she tells Shepherd and the rest of the team that Trout has been using them for his own agenda and not on government authorized missions. They are divided over whom they believe, could this be the end of the Special Ops Force?
