The Diplomat season 2 was one of Netflix’s most highly-anticipated second outings, and it returned in late 2024 with a triumphant six-episode stint. The second season of The Diplomat follows-up the eight-episode series starring Keri Russell as Kate Wyler, an American diplomat and the United States Ambassador to the United Kingdom. She and her career diplomat husband Hal Wyler (Rufus Sewell) struggle with their contentious relationship and, at the same time, try to stop a war after a British aircraft carrier is bombed near Iran.
