Read the complete plot summary and ending explained for Slave of the Cannibal God (1978). From turning points to emotional moments, uncover what really happened and why it matters.
Susan Stevenson, [Ursula Andress], is trying to find her missing anthropologist husband, Henry, in the jungles of New Guinea. She and her brother Arthur Weisser, [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 sits off the coast on the island of Roka. The locals say the mountain is cursed, and the authorities will not permit expeditions there, so the searchers secretly slip into the wild to begin their quest. They make it to the island and, after facing dangerous wildlife such as anacondas, alligators, and tarantulas, meet another jungle explorer, Manolo [Claudio Cassinelli], who has been staying at a nearby mission camp and agrees to join the expedition.
Each person arrives with their own hidden motive for coming to the island, beyond finding Susan’s missing husband. Susan and Arthur are secretly after uranium deposits. Foster explains that he had been on the island a few years earlier, was captured by a tribe of primitive cannibals, and has returned only to wipe them out if they still exist. The group presses on toward the mountain, and tragedy soon follows: Arthur is killed, and Manolo and Susan are captured by the cannibals and taken to their cave. There, they discover the natives worshiping the skeletal remains of Susan’s husband, and they find a photo of Henry and Susan as a couple. The tribe can hear Henry’s Geiger counter ticking and believe his heart is still beating. They treat Henry as their Cannibal God, and Susan is spared while others are consumed. The tribe coats her entire body with an orange cream by two native girls, first appearing as a honey-like torture, but it marks her transformation into a Cannibal Goddess after she tastes and eats Arthur’s cooked remains. A cannibal’s attempt to rape Susan is thwarted when the aggressor is emasculated and killed as punishment. Manolo is tortured and bound, but Susan and Manolo eventually manage to escape, having endured a brutal ordeal.

In the tangled heart of New Guinea’s rainforest, a relentless search begins. Susan Stevenson is haunted by the disappearance of her anthropologist husband, Henry, and enlists her brother, Arthur Weisser, to follow the faint trail into an uncharted wilderness. The jungle’s towering canopy, echoing calls of unseen creatures, and the whispered legends surrounding the forbidden mountain of Ra Ra Me create a landscape that feels both alluring and hostile. Their journey promises a clash between personal desperation and the untamed mysteries that hide beyond the mapped world.
Joining them are a handful of uneasy allies. Professor Edward Foster, a scholarly explorer with his own academic obsessions, brings a measured, almost clinical curiosity to the expedition. The rugged wanderer Manolo arrives from a distant mission camp, his weathered experience hinting at a deeper connection to the island’s secretive past. Each traveler carries motives that linger beneath the surface—curiosity, ambition, and perhaps something more concealed—setting up a delicate web of trust and tension as they press onward toward the mountain’s shadowed summit.
Beneath the humid stillness, rumors of a secluded cult devoted to a cannibal deity swirl among the local folklore. The very air seems tinged with an ancient dread, as rituals driven by death and a thirst for blood are said to linger in hidden clearings and stone‑carved caves. The sense of looming danger is palpable, a constant undercurrent that transforms the expedition from a simple rescue into a confrontation with forces that defy reason. The jungle becomes a character in its own right—beautiful, unforgiving, and brimming with secrets waiting to be uncovered.
As the group delves deeper, the line between explorer and prey blurs, and the stakes rise beyond the personal quest. The oppressive humidity, the chorus of wildlife, and the ever‑present whisper of an unseen presence create a relentless atmosphere of suspense. In this treacherous world, every step forward is a step further into the unknown, where the true nature of the jungle—and what lies at its heart—may change each traveler forever.
