Kate Wyle (Keri Russell) is the new U.S. Ambassador to the United Kingdom. Supposedly in Afghanistan, she feels right at home in a crisis zone, but not so much in a historic house. War is brewing on one continent and boiling on another. Kate must defuse international crises, build strategic alliances in London, and adjust to her new position in the spotlight—all while trying to maintain her marriage to career diplomat and political star Hal Wyle (Rufus Sewell). From showrunner Deborah Kahn (The West Wing, Homeland), The Diplomat is a contemporary political drama at stake, about the long-standing turbulent relationship between nations and people. Also starring is David Gyasi, Ari Ann, Rory Kinnear and Otto Essendoh, with Deborah Kahn, Janice Williams and Keri Russell serving as executive producers.
