The Man from U.N.C.L.E. (1964)

S1E8 The Double Affair

THRUSH devises a plan to create a doppelgänger of Solo, enlisting the alluring Serena (Senta Berger) to help Darius Two (Michael Evans) capture the real Solo. They replace him with the imposter as U.N.C.L.E. attempts to transfer the code for a top-secret weapon. Illya and stewardess Sandy Wister (Sharon Farrell) soon catch on to the deception. Meanwhile, the genuine Solo manages to break free, leading to an intense showdown where he confronts his own double.
