In the heart of London, a devastating explosion rocks the city and turns US Ambassador Kate Wyler’s (Keri Russell) life upside down. As she struggles to piece together the shattered remains of her career and personal life, a shocking truth comes to light: the attack that brought her to the UK was not orchestrated by a rival nation, but by forces within the British government itself.
With her world crumbling, Kate is left with only one ally she can trust—her estranged, almost-ex-husband Hal Wyler (Rufus Sewell), who is not only alive but deeply entangled in the conspiracy. As they navigate the murky waters of betrayal and treason, Kate must juggle a fractured marriage, a complicated relationship with British Foreign Secretary Austin Dennison (David Gyasi), and a perilous visit from Vice President Grace Penn (Allison Janney).
The stakes have never been higher as Kate uncovers secrets buried deep within the corridors of power. Amidst the grandeur of stately homes and the ritual of high tea, lies a deadly game of high treason that could change the fate of nations.
From the brilliant mind of creator Debora Cahn, the Emmy-nominated series The Diplomat returns with a gripping second season. With Janice Williams, Alex Graves, and Keri Russell as executive producers, and a stellar cast featuring Ali Ahn, Rory Kinnear, and Ato Essandoh, prepare for a season of unrelenting suspense, complex politics, and unforgettable drama.
