As part of Collider’s Exclusive Preview, we’re debuting one of the first images from The Diplomat Season 3 — and it’s a tense one. The still features Keri Russell’s Kate Wyler mid-phone call, the kind of white-knuckle moment the series has mastered over its first two seasons. Fans won’t have to wait much longer to see what’s rattling her this time, as Netflix has confirmed the show will return before the end of the year.

The political drama, created by Debora Cahn, was renewed for Season 4 not long ago — well ahead of the Season 3 premiere — a sign of confidence in Russell’s Emmy-nominated performance and the show’s growing momentum. The upcoming season reunites Russell with Rufus Sewell’s Hal Wyler and introduces Bradley Whitford as First Gentleman Todd Penn, alongside Allison Janney as President Grace Penn. Whitford, fresh off roles in The Handmaid’s Tale and Godzilla: King of the Monsters, joins a cast that also includes David Gyasi as Foreign Secretary Austin Dennison, Alex Graces, Peter Noah, and Eli Attie.

What to Expect From ‘The Diplomat’ Season 3?

Season 3 finds Kate in the exact position she’s spent years trying to avoid: the Vice Presidency. After accusing Vice President Grace Penn of hatching a terrorist plot — and admitting she only wanted the VP job — a series of deadly machinations left the President dead and Grace in charge of the Oval Office. Meanwhile, Hal’s behind-the-scenes push to elevate Kate into political power hasn’t slowed, forcing her to navigate new alliances, an uneasy friendship with Dennison, and a surprising rapport with Todd Penn.

The still we’re debuting captures that signature Diplomat tone: layered political intrigue wrapped around a human moment of pressure, mistrust, and decision-making. For a show that thrives on the fine line between personal stakes and geopolitical tension, one image can say a lot — and this one promises another season where the balance is more precarious than ever. As for what we can expect? Executive producer Janice Williams said in an interview with ScreenRant that the relationship between Hal and Kate is progressing.

“I think you saw in Season 2 they broke apart and they came together. That is the state of their union. That has always been the state of their union—to be madly in love with someone and [have rage] toward them all at the same time.”

The Diplomat Season 3 will premiere later this year. Stay tuned to Collider for more updates and coverage of the series, and watch the first two seasons of The Diplomat on Netflix.
