April and Mark infiltrate a youth clinic on Rejuven Isle somewhere in Scandanavia. A Baroness (played by Gena Rowlands) is blackmailing wives of important men and forcing them to pay for the youth injections with top secret documents. The Girl from U.N.C.L.E. is an American spy-fi TV series that aired on NBC for one season from September 16, 1966 to April 11, 1967. The series was a spin-off from The Man from U.N.C.L.E. and used the same theme music composed by Jerry Goldsmith, which was rearranged into a slightly different, harder-edged arrangement by Dave Grusin. The series starred Stefanie Powers as April Dancer, Noel Harrison as Mark Slate, and Leo G. Carroll reprised his Man from UNCLE role as Alexander Waverly.
