The film opens with Gail Cooper (Holly Palance) traveling to her ex-husband Nick's (Jack Jones) apartment in Los Angeles in order to remove some of its more valuable items. It soon becomes apparent that while Nick (a successful singer) isn't at home, someone is clearly there. The anonymous person watches Gail take a phone call from a reporter asking about the couple's divorce and inquiring as to when Nick will release his next album, as he's been on a six year hiatus since marrying Gail. As the phone call ends and Gail walks around the house she is ambushed and murdered by the person, who is wearing an old lady mask and women's clothing.
The story focuses on a British photographer, John Bradley, who is sent into the Thai rain forest to take wildlife photographs. While on assignment, a tribe native to the area takes him captive.
