"The Americans," which premieres its fifth season Tuesday night on FX, follows KGB spies living as a married American couple with kids in the suburbs of Washington, D.C., during the early 1980s. The show stars Keri Russell and Matthew Rhys as Elizabeth and Philip Jennings.

Last year, FX renewed the show for a fifth and sixth season, with the sixth being its last. (You can watch the first four seasons on Amazon Prime.)
