Thrush captures Napoloen Solo and replaces him with a look-alike to infiltrate UNCLE and an operation called "The August Affair". While Solo is being held prisoner, Illya Kuryakin becomes suspicious by the unusual behaviour of his friend, and slowly starts to realise what has happened. The real Solo must escape and stop his Thrush double before it's too late. This film is made up from "The Double Affair" (11/17/64) and "The Four Steps Affair" (02/22/65) from the first season of The Man From U.N.C.L.E. Written by Daniel Bolton
