Set in the American West, a hell-bent boy and his father come up against a former marshal who isn't above breaking the law. There's no taming Billy Blanchard. He's cut from the same rough cloth as his father, Jacob, the man who built the town of Black Horse Creek from nothing. Jacob takes pride in Billy's lawless, wild ways. But when the boy returns home with a stolen horse, having just killed a US Marshal, Jacob knows trouble will be coming. Called in on special assignment, enigmatic former deputy marshal Grayson is asked to find Billy. The marshals would prefer to have him brought in alive. But Grayson knows Billy. He knows Billy's father. And he knows that things don't always go the way the law would like.
