Massacre in Dinosaur Valley (1985)

Michael Sopkiw hitches a ride to Brazil to dig up some dinosaur bones. Once in Brazil he gets in a few tangles with the locals and manages to secure a ride on a charter flight deep into Amazonia. All hell breaks loose as the plane crashes deep in the heart of the jungle, leaving Sopkiw, megalomaniac Soares, and a bunch of super models on their own to trek back to society. The group runs into cannibals, quick sand, murderous animals, and a renegade mine run by slave owners.
