As the U.S. ambassador to the U.K., Kate attempts to prevent another world war after a British aircraft carrier was bombed. She spends season 1 and season 2 uncovering who was behind the bombing and finally learns that U.S. Vice President Grace Penn (Allison Janney) was responsible for the attack.

Meanwhile, Kate’s husband, former U.S. ambassador Hal Wyler, who narrowly survived a car bombing, continues to meddle in diplomatic affairs and remains determined to get Kate into the White House.

“I’ve already read everything of season 3,” Russell toldRolling Stone. “It’s so good in the way I want things to be good, and I just can’t believe that it’s still getting better.”

For fans who have already finished allsix episodes ofThe Diplomatseason 2, here is everything to know about season 3, including production details and who from the cast is returning.

Netflix has yet to release plot details forThe Diplomatseason 3, but viewers will likely see Vice President Penn’s inauguration following the death of U.S. President William Rayburn.

Considering Kate is aware of Penn’s involvement in the deaths of 25 members of the Royal Navy, it’s unclear whether she will be asked to serve as vice president or, worse, fired from her role as ambassador.

As for Kate and Hal’s tumultuous marriage, are they still headed for divorce?

“It may be a marriage on its way out, but sometimes a marriage that seems like it may be on its way out is just in the middle of a change,” Sewell told PEOPLE in November 2024. “They’re fantastic together and apain in the ass togetherand it’s all part of the same thing.”

Season 2 ofThe Diplomatended with yet another cliffhanger.

In the final minutes of the season, Penn has a very blunt conversation with Kate, instructing her to keep quiet about her knowledge of the vice president’s involvement in the bombing of the HMS Courageous and to “stop chasing” the political position.

Simultaneously, Hal is on a call with President Rayburn to brief him on Penn’s traitorous schemes. The information ultimately causes Rayburn to have a fatal heart attack, and season 2 ends dramatically with the Secret Service sprinting to protect Penn, who will soon become the leader of the free world.
