Thinking that being on the run can be no worse than the torment of phoney incrimination and punishment, Billy Finch escapes from the brutal prison of Great China Wash. Riding many miles south, a vengeful search leads Billy to Walnut Bench and its sheriff, Bigg Harmer, who, in a serpentine twist of fate, is seeking the same man. Billy decides to strike a deal and joins a posse of hard-bitten gunmen and outlaws with prices on their heads in a thrilling, action-packed trip across the border into Mexico.
