Jack 'Diamondback' McCall is having a steady run of bad luck. The Mexicans want him in prison. The Apaches want him dead. Bounty hunters want the price on his head and an old foe wants revenge. Jack now carries a tarnished reputation and the gunmen just keep coming. Soon, he's trapped in a clever plot of retribution as he faces an enemy who seems to anticipate his every move. What begins as a matter of honor soon turns deadly, with Fawn, the beautiful Indian woman he loves, and his partner, Dakota Dan, caught right in the middle. Jack will do what he must to save Fawn, but even his dazzling speed with a six-gun isn't enough. Things quickly go from bad to bloody. And then there's 'The Canyon of the Devil's gold'.
