Black Desmond was a swashbuckling, dashing figure -- one of the most brutal and murderous the Southwest had ever known. Now he has transferred his rustling, robbing, and killing operations to a sparsely settled area of Montana. And it's there that he meets his match in Sheriff Wyster and his posse. In the desperate running battle with Desmond's gang, two of the sheriff's sons are killed. But Wyster's son Alvin still lives -- and so does the young son of Black Desmond. This is a story of courage and love of the law pitted against cunning, greed, and cruelty.
