Set in the world of Israeli diplomacy across multiple postings — Paris, Washington, Berlin, Tokyo — The Diplomat's Wife follows Ronit Kessler, 40, whose official identity is the Israeli Ambassador's wife and whose actual role is a deniable intelligence asset for Mossad, using the specific access that a diplomat's spouse receives (every private dinner, every social occasion, every conversation considered off the record because she is ornamental rather than official) to gather intelligence that the institution cannot acquire through formal channels. Three seasons track three postings: Paris (Season 1), Washington during a major bilateral crisis (Season 2), and Berlin during a historical confrontation with Holocaust restitution issues (Season 3). Her marriage to Ambassador Eli Kessler is genuine, complicated, and built on complete mutual knowledge of what they both actually do — making their relationship the series' most unusual love story.
