Gringo (Stuart Whitman) is a semi-crazed adventurer who once went into the jungle with his friends to find treasure and returned years later unable to remember his own name and with the shrunken heads of his friends in a bag.
But naturally he now wants to return to the jungle with a group of fellow adventurers and others after the loot including former Nazi Klaus (Donald Pleasence) and Barbara (Ann Sidney) who has found some diamonds but doesn't seem to have found the correct accent to use...
The film isn't very good to very honest. The narrative jumps around all over the place and is often shamelessly exploitative for example including scenes with naked native women wrestling and another one where a native eats a tarantula! It also has massive amounts of gore and violence. The sheer disjointed awfulness however makes it fairly entertaining.
