The Diplomat plot

The Diplomat follows Katherine Wyler, the newly appointed US ambassador to the United Kingdom, who was hoping to be sent to Afghanistan rather than London. But as threats of war continue to bubble over across the world, Kate must diffuse international crises, forge strategic alliances, and adjust to her new life in the UK. Yet her new career also puts pressure on her long-term marriage to fellow diplomat Hal Wyler, a former ambassador who has since been reduced to the sidelines. He's dying to interfere and tensions erupt! Then a big crisis happens in the Persian Gulf and it all kicks off...

* Here's an interview below with Keri Russell and Rufus Sewell talking all things The Diplomat...

Debora Cahn on creating The Diplomat for Netflix

"The Diplomat is a show about the transcendence and torture of long-term relationships,’ says showrunner Debora Cahn. "It’s hard to keep a relationship going, be it a marriage or a military alliance. We change, the world changes, and yet we want these relationships to go on forever. 

"It’s a show about a bunch of good people doing their best to keep their global and personal partnerships intact without killing each other. In the world of diplomacy, you’re dealing with a lot of rule-bound, protocol-driven behaviour, but underneath all that, these are people who sweat, and spill coffee on their clothes, and forget the name of the person they’re talking to. All of that is always bubbling under the grandeur and majesty of working with heads of state."
