Jesse Stall and his brothers, Ben and John, led a life of crime until they were caught by Sheriff Taddius Jacobs and sent to Yuma territorial Prison. Released from Yuma they sought revenge on the man who had put them there. Jesse may have been alright shooting 'Tad' in the back and leaving him for dead for the killing of his brother Ben, but when he kidnapped 8 year old Jenny out of spite, it raised Devil's ire; an eighteen hand thoroughbred stallion who would kill anyone who turned their back on him, except Taddius Jacobs'. Now, pitted against the wilds of Central Colorado Territory the Devil and Jenny must survive the wrath of Mother Nature, renegade Indians and wild animals if they hope to ever get back home.
