The Italian title of Make Them Die Slowly was Cannibal Ferox. Either way, the point is made. An altruistic team of anthropologists heads to the jungles of South America to study cannibal life. They discover that the cannibals have been enslaved by drug lords and put to work harvesting various controlled substances. Ultimately, the natives revolt against their captors. They go on an omniverous rampage, sparing no one-not even those likable scientists. This is what is known as a "splatter" film, and not without very good reason.
