The Debora Cahn creation, Netflix’s ‘The Diplomat,’ is a political thriller drama series that revolves around Kate Wyler and her duties as the United States ambassador to the United Kingdom amidst an intense international crisis. The third season picks up right after President Rayburn dies by the end of the sophomore round. When Kate, Hal, and Grace Penn receive the news of the President’s demise, Grace automatically assumes the position of the new commander in chief.
Upon finding out that President Rayburn was on the phone call with Hal when he passed away, she wants to know what the two talked about in the President’s last moments.
