Six American graduate students studying apes in the African jungle discover a new species of killer chimpanzees that could prove to be the most formidable threat ever known to humankind. Upon first spotting this bizarre new breed, Greg, Dani, Amy, Josh, Sydney, and Seth were all assured by their highly-esteemed professor (F. Murray Abraham) that they have all been part of a discovery that could change the very face of science. Survival instinct soon takes over, however, when a typical study in animal behavior becomes a brutal struggle to escape a relentless predator with unparalleled strength and speed. As the serenity of the wilderness is suddenly shattered by the blood-curdling screams of man, Mother Nature proves just how little we truly understand about the savagery of the jungle.
