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" (Matthew Rhys) and "Elizabeth Jennings" (Keri Russell), who have two children – 14-year-old "Paige" (Holly Taylor) and 11-year-old "Henry" (Keidrich Sellati), 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. Their neighbor, "FBI Agent Stan Beeman" (Noah Emmerich) has already come dangerously close to discovering their secret, but was thwarted by "Nina" (Annet Mahendru), his KGB mole and paramour. Torn between his wife "Sandra" (Susan Misner) and his deepening feelings for Nina, Stan is completely unaware that the beautiful Russian is actually a double agent, reporting on him to the KGB. Philip has been more successful handling his mole within the FBI, "Martha" (Alison Wright), assistant to Stan’s boss, "Special Agent Gaad" (Richard Thomas). Romancing Martha under the guise of one of his cover identities, an FBI bureaucrat named "Clark," Philip has secured her unquestioning loyalty…by marrying her. Meanwhile, in the Jennings’ house, Paige has become increasingly suspicious that her parents are hiding something.
