It was supposed to look like a suicide, but the death of a government contractor on a ski-lift near Denver was actually the handiwork of enemy spy Glen Parmenter (
Barry Morse). In order to ensnare Parmenter, Erskine (Efrem Zimbalist Jr.) poses as drug-addicted government employee, willing to be "corrupted" into handing over top-secret information to the Other Side. Managing to infiltrate Parmenter's mountain-cabin headquarters, Erskine finds out that the female of the species--namely Elaine Ross (Victor Shaw)--can be just as deadly as the male in the espionage business. ~ Hal Erickson, All Movie Guide
