Netflix’s Emmy-nominated political thriller The Diplomat is returning to the screen. Alongside announcing the release date of the upcoming season, the streaming giant released yet another preview, giving fans a peek into what to expect. The new teaser for season three opens with Ambassador Kate Wyler, played by Keri Russell, sharing a warning with the viewers.
“A terribly flawed woman is now the president, and only we know just how flawed,” she says as Grace Penn, played by Allison Janney, swears in as the new President of the United States. She steps into the Oval Office after President Rayburn’s (Michael McKean) sudden death in season two. Fans of the show will remember that in the last season, Kate and her husband, Hal Wyler, played by Rufus Sewell, had discovered Grace’s connection to the British warship attack that was shown in the first episode of season one. In the final episode of season 2, Grace explained her rationale behind the attack to Kate in a tense exchange.
The Diplomat Season 3: Release Date
The 50-second teaser also shows Grace officially being sworn in as the president and introduces her husband, Todd Penn, played by Bradley Whitford. While Todd has been mentioned in the series since the first season, it will only be in season three that viewers see him make an appearance. Back in season one, he had misplaced a part of an NIH grant, which almost ruined his wife Grace’s career even before she became vice president. The latest teaser of The Diplomat ends with Hal telling Kate, “You will be in the White House watching what she does all the time.”
Netflix shared the teaser through their official social media accounts, writing, “Keri Russell. Rufus Sewell. Allison Janney. Bradley Whitford. The Diplomat returns OCTOBER 16.” The new season of the show will premiere on the OTT platform on October 16, and this time, instead of the shorter six-episode second season, fans will enjoy an eight-episode season.
The Diplomat Season 3: Plot And Cast
The official description of The Diplomat’s season three describes Kate Wyler’s new reality as “the particular nightmare that is getting what you want. She just accused Vice President Grace Penn of hatching a terrorist plot and admitted she’s after the VP’s job.” Now, with Grace in power, Hal pushing Kate to become the new vice president, and shifting alliances around her, Kate would face challenges she never expected.
Previously, in an interview with The Hollywood Reporter, Keri Russell and Rufus Sewell talked about the ending of season two, revealing that the couple made a “very powerful enemy.” The new season will also explore Kate’s increasingly complicated friendship with Foreign Secretary Austin Dennison (David Gyasi) and her uneasy new dynamic with Todd Penn.
The Diplomat, created by Debora Cahn, has already been renewed for season four. Alongside the lead pair, the series will also feature Ali Ahn, Ato Essandoh, Celia Imrie, Nana Mensah and Miguel Sandoval.
