The Diplomat Season 4 trailer: Kate Wyler takes on White House gone 'over the line'
The new trailer for The Diplomat Season 4 shows Kate Wyler confronting President Grace Penn over a covert military incursion. The preview signals a worsening US-UK crisis as shifting alliances strain both power and marriage.
Kate Wyler has spent three seasons navigating diplomatic crises, political games and a marriage that refuses to stay simple. Now, she may have to take on all three at once. Netflix has released the full trailer for The Diplomat Season 4, and Keri Russell’s Kate is facing perhaps her most dangerous problem yet.
President Grace Penn (Allison Janney) and Vice President Hal Wyler (Rufus Sewell) have secretly joined forces over a powerful Russian weapon, with their actions threatening to push the US towards war. Kate, unsurprisingly, is not taking it quietly.
