This peculiar spaghetti western was inspired by the success of the American television series Macho Callahan with Italian audiences. Jeff Cameron (a pseudonym for actor Geoffredo Scarciofolo) plays Macho Callaghan, with spelling changed for legal reasons. Macho is the sole survivor of a bloody raid led by Butch Cassidy's Wild Bunch. With the help of a kindly priest (Klaus Kinski), Macho infiltrates the gang, upsetting the Sundance Kid. Sundance tries to discredit Macho by staging a vicious outlaw battle, not knowing that both the newcomer and the priest are actually Pinkerton agents. A silly storyline and weak performances are somewhat offset by the cinematography of Aristide Massaccesi and the opportunity to see Klaus Kinski in a rare heroic role, but this one remains for genre completists only. Demofilo Fidani directed using the pseudonym "Miles Deem." ~ Robert Firsching, Rovi
