The plot of the film established a formula that would become iconic. An anthropologist named Harold Monroe (Robert Kerman) leads a rescue mission into the Amazon jungle to find a missing documentary film crew. He eventually recovers their footage. However, when he screens the "found footage," he discovers that the crew were not innocent documentarians. Instead, they were violent, sadistic individuals who staged brutal acts of violence and torture against indigenous tribes to create a sensationalist film. In the end, the crew meets a horrific end at the hands of the very people they terrorized.

To clear his name, Deodato was forced to produce the "dead" actors in a courtroom to prove they were alive and well. The murder charges were subsequently dropped.

Riz Ortolani’s hauntingly beautiful, melodic musical score is also widely celebrated for creating a stark, unsettling juxtaposition against the brutal imagery on screen.
