In 1980s Washington, D.C., KGB sleeper agents Philip and Elizabeth Jennings take extreme measures to continue their mission and keep their true identities hidden when Stan Beeman, an FBI Counterintelligence agent, moves in across the street from them.

The stakes have never been higher for Philip and Elizabeth as personal and professional dangers continue to challenge the Jennings' mission.

In the sixth and final season, Philip and Elizabeth’s ability to protect their cover and family’s safety deteriorates. The Jennings struggle to maintain a smokescreen of normalcy, especially around their son who remains ignorant of the spies in his midst. With Gorbachev in power in the Soviet Union, the winds of change are sweeping through Russia and America creating new perils.
