Synopsis by Karl Williams
Some extra footage was added to segments of two episodes from the television series The Man from U.N.C.L.E. (1964-68) to create this feature film-length espionage adventure that was released theatrically in some countries to cash in on the James Bond craze. Ordered by their secret organization U.N.C.L.E. to stop the sinister group THRUSH from obtaining a top-secret nuclear weapon, spies Napoleon Solo (Robert Vaughn) and Illya Kuryakin (David McCallum) travel to Switzerland. Once there, Solo is lured into a trap by a comely enemy agent, Serena (Senta Berger). Kidnapped by THRUSH, Solo is replaced with an exact double who infiltrates U.N.C.L.E. Kuryakin eventually becomes suspicious due to his friend's odd behavior and takes steps to learn the truth, while Solo attempts to escape from captivity and stop THRUSH's plot to get its hands on the weapon. The episodes represented in the film are "The Double Affair," which first aired November 17, 1964, and "The Four Steps Affair," which originally aired February 22, 1965.
