Somewhere deep in the Amazon jungle, middle-aged prospector Jeff Jensen (Nehemiah Persoff) is attacked and nearly killed by his young wife, Marie (Cara Williams). Concluding that his wife has gone insane, Jeff commiserates with his partner, Mike (Mark Richman), and together they agree that Marie must be taken out of the jungle to see a "head shrinker" -- that is, a psychiatrist. Little does Jeff suspect that Marie's display of madness was carefully contrived so that she could run off with her boyfriend, Mike! Unfortunately, the lovers' "perfect" scheme comes to a gruesome end, thanks to a little matter of miscommunication....
