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 - 13-year-old Paige (Holly Taylor) and 10-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.
When Philip and Elizabeth are ordered to go through with a meeting that could potentially be a set-up, they find themselves confronted with unexpected truths about their relationship. Stan's investigation puts him and the FBI even closer to Philip and Elizabeth.
One of Elizabeth's agents has key intel for sale, but she and Philip find themselves taking increasingly greater risks for what could well be a set-up. Meanwhile, Stan's pursuit of Directorate S suddenly begins to yield unexpected results.
Events in Moscow strike a personal chord for Elizabeth, leading her to take on a dangerous mission she can't complete without Philip's help, and placing the couple on a collision course with both Grannie and the FBI.
Stan pursues a lead that puts him on the trail to one of Gregory's crew members, closing the gap between him and Elizabeth, and reigniting some of the deepest conflicts between her and Philip.
Philip and Elizabeth are put to the test when a routine mission goes horribly wrong. Stan and the FBI are pushed to their limit when one of their own goes missing.
