 Utterly devastated by causing his bride s drowning death while drunk-driving, Harry (John Phillip Law) leaps off a railroad trestle into dark waters below. He is fished out and sent to a private sanitarium run by Dr. Brewer (Arthur Braham) and Dr. Fargo (Sharon Ratcliff). The two have a nefarious operation inside: selling beautiful young girls to Middle-Eastern sheikhs for their harems. Under mind control and hypnotic drugs, Harry is routinely sent out as a handsome bait to lure more captives. In his lucid moments, Harry explores upstairs after filching keys from sadistic orderly Otto (Richard Moll). Admitting himself into off-limit quarters, he surprises a beautiful woman who claims she s movie star Marilyn Monroe, that another body was substituted for hers and that somebody rich and powerful had her sent here. She pleads for Harry s help in escaping. They eventually fall in love and, after harrowing and horrible ordeals below, including a fight to the death with the enraged Otto, flee the place, but not before Brewer and Fargo meet their ironic fate.
