In New York City, a TV news reporter recounts the details surrounding the mysterious disappearance of a documentary film crew who has gone missing in the jungles of South America for two months. The reporter introduces them as Alan Yates (Gabriel Yorke) the director; Faye Daniels (Francesca Ciardi) his girlfriend and script girl; and friends Jack Anders (Perry Pirkanen) and Mark Tomaso (Luca Giorgio Barbareschi) who work as cameramen. They were last seen departing from the remote Columbian town of Leticia which sits deep in the jungle on the border points between Brazil and Peru, to document the existence of cannibal tribes in the jungle. NYU's noted anthropologist Professor Harold Monroe (Robert Kerman) is assigned the task by the university to find out what happened to the conceited, and over-confident film crew.
