Phil Sundeen thinks Deputy Sheriff Kirby Frye is just a green local kid with a tin badge. And when the wealthy cattle baron's men drag two prisoners from Frye's jail and hang them from a high tree, there's nothing the young lawman can do about it. But Kirby's got more grit than Sundeen and his hired muscle bargained for. They can beat the boy and humiliate him, but they can't make him forget the oath he has sworn to uphold. The cattleman has money, power, and guns on his side, but Kirby Frye is the law in this corner of the Arizona Territories, and he'll drive a rich man to his knees to prove it.
