After low-level CIA analyst Joe Turner returns from lunch to discover that everyone in his office has been killed, he goes on the run trying to elude hit men and uncover the truth about who is behind the murders.

Joe escapes from IEP but his safety remains in doubt. Unsure who to trust, Joe turns to Bob Partridge. A task force is assembled to investigate the massacre. With his best friend's life now in danger, Sam struggles with his next move.

News of the massacre at IEP spreads; Bob seeks an ally after learning that he must remove himself from the operation to find Joe; Reuel questions Mae's knowledge of Sam's recent behaviour.

Joe is forced to flee with Kathy; Marty suspects there may be a mole on her team; Reuel grows increasingly concerned about Bob's loyalty; Joe's search for answers leads him to two important people from his past.

Reuel and Marty hope Caleb Woolf will be the secret to Joe's capture. Bob tries to extract information from Joubert. In Riyadh, a plan is set into motion.

Mae is tormented by lingering questions surrounding her husband's death. Caleb informs Joe of his CIA source. Joubert and Boyd cross paths at Kathy's house and make a crucial discovery.
