Set in the year 1873, professional gambler Stubby Preston arrives in the Wild West town of Salt Flats, Utah with plans to work the local casino but is arrested by the sheriff the moment he steps off the stagecoach. What Stubby doesn't know is that a group of locals have planned a vigilante attack on the casino that night, which the sheriff plans to turn a blind eye to. The only criminals to survive are those who were in the jail when it happened: Stubby, a pregnant prostitute named Bunny, a disturbed but gentle black man named Bud, and an alcoholic named Clem.
