Kendall Cross (as Sister Elizabeth) and Susan Hogan (as Sister Katherine) are two criminals making their way west dressed as nuns, robbing bad men on their way to a gold town. When they reach their destination they realize that the town is under the thumb of an evil tyrant. Soon they devise a plan to break into his bank through the wall of his saloon, enlisting the help of the impoverished townfolk to force him to close the saloon on Sundays so they can perform this deed. But should they really steal the money and skip town, or help the poor people there? And can Sister Katherine come to terms with her questionable past? They can indeed, but only with the help of the Dead Man's Gun.
