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 grows more passionate and genuine by the day, but is constantly tested by the escalation of the Cold War. Tensions heighten upon the arrival of a new neighbor, Stan Beeman, an FBI agent.

Philip and Elizabeth discover that their murdered colleague Robert had a wife they never knew about. As they try to determine what she knows and where her allegiance lies, Stan’s investigation into Robert’s death puts him hot on their trail.

When an assassin attempts to kill President Reagan, Philip and Elizabeth scramble to handle the fallout within the KGB. Meanwhile, Stan pressures his source within the Rezidentura to find out if the KGB was responsible for the attempted assassination.

A mole hunt within the KGB causes suspicion amongst allies and shatters trust within the Jennings’ marriage. Meanwhile, Stan’s plan to keep his mole safe puts her at even greater risk of discovery.
