In this tale of bloody redemption, Dag Enberg is a shotgun rider for Arizona's Yuma Stage Line, and he's one of the best in the business. When a group of outlaws led by Cougar Ketchum kidnaps Enberg's pregnant wife and threatens to kill her if Enberg doesn't turn over a valuable strongbox, Enberg turns over the box without a fight. The owner of the strongbox, Logan Cates, believes that Enberg has thrown in with Ketchum. A bloody war breaks out...as well as a desperate chase into Mexico for the stolen gold and Enberg's woman.
