Set during the Cold War period in the 1980s, The Americans is the story of Elizabeth and Philip Jennings, two Soviet KGB officers posing as an American married couple in the suburbs of Washington D.C. and their neighbor, Stan Beeman, an FBI Counterintelligence agent.

A commercial airliner suddenly reappears after being missing for five years. As those aboard reintegrate into society, they experience guiding voices and visions of events yet to occur, and soon a deeper mystery unfolds.

Two KGB spies are posing as Americans in suburban Washington D.C. shortly after Ronald Reagan is elected President. The arranged marriage of Philip and Elizabeth Jennings, who have two children—13-year-old Paige and 10-year-old Henry, who know nothing about their parents' true identity—grows more passionate and genuine by the day, but is constantly tested by the escalation of the Cold War and the intimate, dangerous and darkly funny relationships they must maintain with a network of spies and informants under their control.
