When Prometheus Jones wins a horse with a raffle ticket he got from Pernie Boyd and LaRue Dill, he knows things won't go smoothly. No way are those two rednecks going to let a black man, even a freeman from the day of his birth, keep that horse. So as soon as things get ugly, he jumps on the horse, pulls his cousin Omer up behind him, and heads off. They hook up with a cattle drive out of Texas heading for Deadwood, South Dakota. Prometheus is a fine hand with a horse and not so bad with a gun, and both skills prove useful as the trip north throws every twist and turn imaginable at the young cowpokes.
