After six years in prison, Mitch Carew returns to Arroyo to seek his revenge on the two men who sent him to prison, shopkeeper Dan Woodworth and Wild Bill Hickok. Carew goads Woodworth into drawing a pistol allowing him to legally kill the elderly Woodworth in self-defence.
Meanwhile, Hickok rescues his ne'er do well friend Larry Armstrong from a lynch mob with the idea that both of them settle down on a ranch. Though Bill finds the love of an Eastern girl, the lure of adventure and the Code of the West lead the pair into trouble, gunplay and vengeance.
