Three bank robbers are about to pull a big heist on a small Arizona mining town, but first they spend time casing the town to get to know the various townsfolk. There's Shelley Martin, a man who is a disappointment to his son because he didn't serve in the war; a seemingly timid bank manager who is a peeping tom by night; an adulterous wife of a local leading citizen; and an Amish farmer who is forced to take violent action when his children are threatened by the criminals.
