Sometimes when a man's luck turns, it turns hard.
Bo Creel and Scratch Morton are experienced drifters, but now the two trail pards are down to their last dime. So they accept the best job they can get, serving as deputies in a boomtown called Mankiller. Their boss is a drunken sheriff named Biscuits O'Brien, who would rather drink, than work. Their tin stars are mighty pretty, but the job starts to get serious quickly, and soon the newly-minted lawmen are standing between a cunning clan of killers and the town's desperate citizens and the killers have a personal vendetta against Bo and Scratch. As the only hope for a besieged town, Creel and Morton now have a chance to become real heroes - that is, if they don't get their heads blown off the minute they stick their snoots out of the door.
