After a "simple brush pass" goes sour, Annie is stranded and on the run in Zurich with Eyal, a Mossad agent who can't be trusted. Meanwhile, as Auggie works to bring Annie home safely, Arthur and Joan are busy trying to track a leak coming from within the CIA ... and Auggie is near the top of the list.

Annie is tasked with investigating a potential national security leak originating from the Senate Intelligence Committee. Elsewhere, Auggie is assigned as a stateside handler for his old special ops unit, and Annie is worried that her brother-in-law, Michael, is cheating on Danielle.
