When Philip and Elizabeth are given an urgent task to plant a bug in Defense Secretary Caspar Weinberger’s office, they risk exposure when an unwilling maid of the Weinberger home refuses to cooperate. Stan closes in on a member of the Soviet Rezidentura in an effort to uncover the identities of deep cover Directorate S operatives.

Stan pursues a lead that puts him on the trail to one of Gregory's crew members, closing the gap between him and Elizabeth, and reigniting some of the deepest conflicts between her and Philip.

Philip and Elizabeth complete their next mission – but not without complications – and Philip's fears about Elizabeth's readiness for action deepen. Stan tracks the KGB walk-in which leads to much praise at work and a deepening of his attachment to, and dependence on, Nina. Meanwhile, Paige snoops into her mother’s family background and Oleg begins to scrutinize Nina’s secret operation.

Just when Philip and Elizabeth think they have a quiet road ahead, an old friend returns to complicate things. Not only do they have to intercept a target who could prove valuable to the Soviet Union, but they also have to take on an important rogue mission without the support of the Centre. Divisions inside the Rezidentura deepen between Oleg and Arkady and there’s an upheaval at the FBI as the chickens come home to roost for Agent Gaad. Meanwhile, Martha’s frustrations threaten to blow Philip’s cover.

Philip and Elizabeth are put to the test when a routine mission goes horribly wrong. Stan and the FBI are pushed to their limit when one of their own goes missing.
