The Man from U.N.C.L.E. confronts his evil twin when THRUSH replaces Napoleon Solo with a surgically altered double--The Spy with my Face. In Switzerland to stop THRUSH from obtaining a nuclear weapon, Solo (Robert Vaughn-"The Man from U.N.C.L.E.") is lured in to a trap by the beautiful agent Serena (Senta Berger--Casts a Giant Shadow), kidnapped and replaced with an evil agent who is physically indistinguishable from Solo. Only when the nefarious doppelganger's actions spark the suspicions of Solo's partner, Illya Kuryakin (David McCallum--"The Man from U.N.C.L.E."), is the plot uncovered and thwarted.
