Susan Stevenson is trying to find her missing anthropologist husband, Henry, in the jungles of
New Guinea. She and her brother Arthur enlist the services of Professor Edward Foster, 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 the mountain is cursed, and the authorities will not allow expeditions there, so the searchers enter the jungle surreptitiously to begin 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, who has been staying at a nearby mission camp, and 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. Foster reveals that 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. Upon arriving at the mountain, Arthur is killed, and Manolo and Susan are captured by the cannibals and taken to their cave. There, they find the natives worshiping the skeletal remains of Susan's husband. The natives can hear Henry's
Geiger counter ticking and believe his heart is still beating. They worship Henry as their Cannibal God and find a photo of him and Susan together. As a result, Susan is spared, and the cannibals feast on other human and reptile flesh. She is stripped naked, bound at the wrists to a pole, and has her entire body smeared with an orange cream by two native girls. At first, it seems this is to be a session of
honey torture, but Susan is turned into a Cannibal Goddess after tasting and eating Arthur's cooked remains. Manolo is tied up and tortured while the others are consumed. One of the cannibals attempts to rape Susan while no one is looking, but is caught and emasculated before being killed as punishment. Manolo and Susan eventually escape after enduring their ordeals. ==Cast==
