Sundown Peters comes to the Southwest to investigate the steady rustling going on and the death of two operatives who had preceded him. He soon realizes that he's run into more than he expected: cattle stealing and murder by the twice-disappearing body of killer Dirk Rawdon and pompous Colonel Willy Nilly, medicine-show proprietor; and a most satisfactory romantic interest in pretty, competent Nancy Scott. When the supposedly dead Rawdon returns, Sundown knows that Faust's gang is up to more than just rustling, but he can prove nothing until he takes a trip out to the Faust ranch and finally untangles the whole far-flung network of big-time lawbreaking.
