Fifteen years removed from service, Napoleon Solo (Robert Vaughn) and Illya Kuryakin (David McCallum) are called back to duty when a former U.N.C.L.E. agent conspires with the evil T.H.R.U.S.H. to extort $350 million from the government with the threat of a nuclear attack. "Avengers" star Patrick Macnee appears in this made-for-television movie as Solo and Kuryakin's new superior, Sir John Raleigh.
