Plot
Susan Stevenson (Ursula Andress) is trying to find her missing anthropologist husband, Henry (Tom Felleghy), in the jungles of New Guinea. She and her brother, Arthur (Antonio Marsina), enlist the services of Professor Edward Foster (Stacy Keach), who thinks her husband might have headed for the mountain Ra Ra Me, which is located just off the coast on the island of Roka.
The locals believe that the mountain is cursed, and the authorities will not allow expeditions there, so the searchers surreptitiously enter the jungle to commence the search. They eventually make it to the island, and after a few run-ins with some unfriendly anacondas, alligators and tarantulas, they meet another jungle explorer named Manolo (Claudio Cassinelli) who has been staying at a nearby mission camp, who agrees to join them in their expedition.
Matters become complicated when it becomes evident that all of them have their own private reasons for coming to the island, none of which include finding Susan's missing husband. Susan and Arthur are secretly looking for uranium deposits, and Foster reveals that he has come there because he had been on the island a few years previously, was taken captive by a tribe of primitive cannibals, and has only returned to wipe them out if they still exist. Foster later dies while climbing up a waterfall.
