Kate Wheeler (Kelly Russell) is the new US ambassador to the UK. She was supposed to go to Afghanistan, she was like a fish in water in the crisis area, but in a house with a long history. I'm not so comfortable. War is brewing on one continent and boiling on another. Kate has to defuse the international crisis, build a strategic alliance in London and adapt to her new position in the spotlight-while trying to maintain her marriage to career diplomat and political star Hal Wheeler (Rufus Seville). Created by show director Deborah Strauss-Kahn ("the White House" and "Homeland Security"), "diplomat number one" is a dangerous contemporary political drama about a long and turbulent relationship between the country and its people. Other stars include David Giassi, Arian, Rory Kinnear and Otto Eisendo, and Deborah Strauss-Kahn, Janice Williams and Kelly Russell are co-producers.
