Umberto Lenzi (CANNIBAL FEROX) directed this atrocious cannibal/religious cult exploitation feature that has become a cult favorite for its awful dialogue, countless scenes of unintentional comedy, copious gore, and a wealth of footage lifted from other cannibal films. Filmed not long after the Jonestown tragedy in Guyana, director Lenzi tries his hand at topicality by having the film revolve around an insane religious leader named Jonas who has taken a small cult of people from America and moved them into a camp in New Guinea that is located right in the middle of cannibal country. When a woman named Diana sends her sister Sheila mysterious footage of an apparently cannibalistic ritual taking place at the camp, Sheila becomes determined to rescue her. Arriving in New Guinea, Sheila hires an ex-G.I. to help her put together an expedition to the camp with the intention of forcibly removing Diana.
