The Diplomat Season 4 Arrives October 15 on Netflix

Netflix’s The Diplomat is scheduled to return for its fourth season on October 15, with all eight episodes set to be released at once. The season will continue the fictional political crisis established in the Season 3 finale, when ambassador Kate Wyler concluded that President Grace Penn and Vice President Hal Wyler had arranged to take a Russian nuclear weapon. The story’s central conflict follows the consequences of that alleged theft. Published descriptions of the new season say Kate and Todd Penn, the president’s husband, will join forces against the alliance between Grace and Hal. Their effort is framed as a struggle to prevent the weapon plot from destabilizing the balance of power in the United States and abroad. In the Season 3 finale, Kate and Hal had pressed British Prime Minister Nicol Trowbridge to accept a plan to entomb a Poseidon nuclear torpedo beneath the sea in concrete. The plan appeared to avert an immediate crisis involving a Russian submarine near the UK, but Kate later learned that the weapon had been taken. She inferred from Hal’s reaction that he and Grace were responsible, according to recaps of the fictional episode.
