A U.S. diplomat turns suicide bomber at a nuclear disarmament summit. Why would a respected official go rogue? It's up to ex-CIA operative Bill Fenner to uncover the mystery. Robert Vaughn's smooth, often playful Napoleon Solo of The Man from U.N.C.L.E. was one of the superspy era's best-known agents, but playfulness takes a backseat to intrigue when Vaughn takes on the role of Fenner for the earnest non-UNCLE maneuverings of The Venetian Affair. Elke Sommer, Felicia Farr, Edward Asner and Boris Karloff are among the players in this trenchcoated tale of Cold War espionage and paranoia based on a book by veteran thriller author Helen MacInnes and flavorfully shot amid the waterways and piazzas of Venice.
