The film tells of a group of Mormons who need to be protected from Mexican gangs. In those moments, two brothers are forced to turn, a drifter and his brother, who is actually a thief who breaks Sharif's true leg. Perhaps this man will be dangerous enough because he leaves him to kill him, and becomes deliberately to hide out of that area.
The movie is a spoof of the traditional 1960s spaghetti Western. In fact, it is to spaghetti as spaghetti is to macaroni and cheese, a dish I have particularly disliked ever since the meat rationing days of World War II.
