FX has been stepping up its drama game in recent years, and one of the network’s most successful original shows is The Americans, starring Keri Russell and Matthew Rhys. The series is a period drama based around two Soviet spies living in America and posing as a married couple in the suburbs outside of Washington D.C.

The series premiere last January brought in 5.1 million viewers, making it FX’s most-watched drama debut ever. Now the network has sent word that the highly-anticipated second season of the show will premiere on February 26 at 10 p.m. ET/PT. If you haven’t caught up on The Americans yet, the network has provided us with a synopsis to let you know what to expect from the series:

The Americans, the most critically-acclaimed new drama of 2013, was recently named by the AFI as one of the Programs of the Year. The series also received the most Television Critics Association Awards nominations of any show this year (four) and earned four Critics’ Choice Television Award nominations. The series stars Keri Russell, Matthew Rhys, Noah Emmerich, Holly Taylor, Keidrich Sellati, Annet Mahendru, Alison Wright and Susan Misner.

Currently in production in New York, 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 (Taylor) and 11-year-old Henry (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 (Emmerich) has already come dangerously close to discovering their secret, but was thwarted by Nina (Mahendru), his KGB mole and paramour. Torn between his wife Sandra (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 (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.
