The Americans is a period drama about the complex marriage of two KGB spies 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. In the series finale, the Jennings face a choice that will change their lives forever. Elizabeth wrestles with competing loyalties, and Philip has an encounter that turns into much more than he had bargained for. With the arms control summit under way, a shocking revelation from Philip throws Elizabeth - and her work - into turmoil. Stan follows a dangerous hunch. Philip and Elizabeth come together for a perilous operation unlike any they've ever had before. Stan and Henry spend a little quality time together. A sudden assignment pulls Elizabeth away from her family at a crucial moment. At the FBI, a major development leads Aderholt to approach Stan about an urgent investigation.
