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.
"The Americans" is a period drama about the complex marriage of two KGB spies posing as Americans in suburban Washington DC shortly after Ronald Reagan is elected President.
The arranged marriage of Phillip and Elizabeth Jennings, who have two children 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.
Complicating their relationship further is Phillip's growing sense of affinity for America's values and way of life. Tensions also heighten upon the arrival of a new neighbor, Stan, an FBI agent working in counter intelligence.
