What Season 3 is about (without the PR fluff)
Keri Russell returns as Kate Wyler, a career diplomat who keeps getting handed jobs designed to chew people up. Season 3 drops her into the immediate aftermath of the presidency-shaking crisis teased at the end of last season. With Grace stepping in as commander-in-chief, the power map shifts fast, and Kate has to manage international fires while her personal life and political future get messier by the hour. It is the show’s sweet spot: sharp, tense, and powered by impossible choices.
Who is in it
Alongside Russell, the lineup includes Rufus Sewell, David Gyasi, Allison Janney, Ali Ahn, Rory Kinnear, and Ato Essandoh, among others.
