U.N.C.L.E. agents Napoleon Solo, (Robert Vaughn) and Illya Kuryakin (David McCallum) witness the aerial destruction wrought on an African village by Dr. Kharmusi using his newly developed “thermal prism”. U.N.C.L.E. then seeks out notorious safe cracker (and former thermal prism researcher himself) Luther Sebastian to help them obtain the device from Dr. Kharmusi. Sebastian is on an island among a religious group called “The Third Way”, a mystical organization with disciples having – except for Sebastian – platinum white hair and all having a belief that when the “Old Man” in their group finally speaks after twenty years of silence The Third Way will have dominion over the world. Wanted in nearly two dozen countries Sebastian agrees to leave the island and help U.N.C.L.E. in return for world-wide immunity from prosecution.
