"Cannonball" Taylor helps Wild Bill Hickok's brother, Dave, escape from jail after he had shot Gus Logan in self-defense. Logan is a henchman of Rance McKee, who is driving ranchers from their lands by filing false homestead claims, and McKee, aware of his past record, is able to force Judge Barlow to issue illegal vacate orders. Wild Bill returns to Tucson and with the aid of Barlow's daughter, Vivian, acquires the needed proof against McKee, but is jailed on a false murder charge.
