‘The Diplomat’ Trailer: Kate Launches High-Risk Investigation Into Prime Minister After Finale Explosion (VIDEO)

Netflix‘s The Diplomat was a massive hit in its first season and is gearing up for its second season with a trailer (above) that answers the biggest questions from Season 1’s explosive finale cliffhanger.

The Keri Russell and Rufus Sewell-starring political thriller debuted at No. 1 on Netflix’s Top 10 list when it premiered in April 2023, racking up over 57 million hours viewed in its first weekend. It’s no surprise then that the streamer renewed the series just 10 days later. Below, we’re keeping track of everything we know about Season 2, from new cast members to plot details to premiere date and more. (Keep checking back, as this will be updated.)

What is The Diplomat About?

The series revolves around Kate Wyler (Russell), the new United States ambassador to the United Kingdom. She is tasked with helping defuse an international crisis while forging strategic alliances and adjusting to her new place in the spotlight. She also has to contend with her deteriorating marriage to fellow career diplomat Hal Wyler (Sewell).

When will The Diplomat Season 2 premiere?

The second season will premiere on Thursday, October 31, 2024. In the meantime, fans can catch up with Season 1 on Netflix.

How did The Diplomat set up Season 2?

In the Season 1 finale, Kate discovered that Prime Minister Trowbridge (Rory Kinnear) was behind the attack on the British aircraft carrier as part of a political power move to help his reelection campaign.

Before Kate could blow things wide open, there was another attack, as a car exploded near Hal and other staffers. As things left off, neither Kate nor the viewers know if Hal or anyone else survived the attack. But the first teaser from the new episodes (see above) confirms he did.

Series creator Debora Cahn told Netflix’s Tudum that going into Season 2, “everything we thought we knew about the Wylers changes, as does everything they think they know about each other.”

Here’s the official description for The Diplomat Season 2: “A deadly explosion in the heart of London shatters US Ambassador Kate Wyler’s world (Keri Russell). Struggling to rebuild the lives that broke and the team that split apart, Kate’s worst fears unfold: The attack that brought her to the UK didn’t come from a rival nation, it came from inside the British government. As Kate chases the truth, her only real ally is her almost-ex-husband Hal Wyler (Rufus Sewell), very much alive, and very much involved. She faces a fraught marriage, a complex dynamic with British Foreign Secretary Austin Dennison (David Gyasi), and a threatening visit from Vice President Grace Penn (Allison Janney).”

Is there a trailer for The Diplomat Season 2?

Netflix released the first footage from the new season on Thursday, September 5, which revealed that Hal was alive and well post-explosion. It also revealed the first look at Janney’s Vice President Penn, who exchanged an intrigued look with Kate.

The tension only builds in the trailer for Season 2 (above) that shows the immediate aftermath of the attack, most importantly how it sets Kate and her team up for an extremely risky investigation into the British prime minister. Some of her team is on board, while others think Kate is being too bold. Janney’s character is also clearly being set up as a new rival for Kate, who is being vetted for the vice presidency herself. Kate is also caring for Hal as he heals from the blast throughout the trailer, though she still seems committed to their living separate romantic lives.

Who is in The Diplomat Season 2 cast?

The West Wing alum Allison Janney is joining The Diplomat‘s second season as the oft-mentioned but yet-to-be-seen Vice President Grace Penn. The multi-time Emmy Award winner is set to guest star throughout the season.

Russell will report for duty once again as Kate Wyler, the US ambassador caught in the middle of an international political struggle. Speaking to Tudum about her role, The Americans actress said, “What I loved is the constant discomfort and sweatiness and nervousness and just overall unpolished quality of her –– matched with the bossiness to everyone, which I think is really funny.”

Season 1’s cast included Sewell, Kinnear, David Gyasi as UK foreign secretary Austin Dennison, Ali Ahn as CIA station chief Eidra Park, Nana Mensah as White House chief of staff Billie Appiah, Miguel Sandoval as US secretary of state Miguel Ganon, Michael McKean as US president William Rayburn, Celia Imrie as Meg Roylin, and T’Nia Miller as Dennison’s sister Cecilia. Netflix has yet to confirm whether all will be returning.
