In Cesare Canevari's psychedelic Matalo! (Kill Him) (1970), double-and triple-crosses abound as a band of outlaws, having holed up in an isolated ghost town, set about terrorizing travellers Ray (Lou Castel) and Bridget (Ana María Mendoza) - only to get more than they bargained for when Ray fights back, armed only with his weapon of choice: a bag full of boomerangs.
