As a wanted man, Dalton never expected to find himself working as a lawman. But that's just what happens when he rides into Green Creek and the alcoholic Sheriff Holstein press-gangs him into becoming his deputy.
Dalton has no choice but to accept the assignment and soon discovers that the whole town has turned against the sheriff. And if that isn't bad enough, Sharky Bigelow's spree of cattle rustling is reopening an old vendetta and shattering the town's peace with a wave of lawlessness.
To bring peace to Green Creek, Dalton must restore faith in the law. But can he succeed with nobody to trust but himself? Will the deadly aim of his six-shooter be enough?
