Sheriff Al Murphy is fed up with Fletcher, Wyoming, a two-bit hole in the wall that has no use for a real lawman. Now they've gone and lynched a powerful Texan's only son and broken Murphy's arm in the process. The streets are about to run with the blood of vengeance - and Murphy's only half alive from hard drinking and hard fighting, and a loss so raw only whiskey numbs the memory of that lone canyon grave.
Soon Murphy's taking them all on: the power-hungry feedstore owner and his rowdy hired hands, and the hardnosed Texas rancher and his small army of cowboys. His only weapons are a sawed-off shotgun, a Colt revolver, his trusty double-action Smith - and the knife-edged courage to go down in a blaze of white heat and glory.
