Young Jimmie Curry’s father is killed unjustly by an enraged mob, and the boy barely escapes the same fate. He shoots two pursuers and assumes they are dead, and in desperation becomes a most unusual outlaw, the Red Devil. He never kills, takes only ill-gained money, secretly returns it to the rightful owners and escapes every pursuit on his remarkable horse Meg. Spoiled Charlie Mark has left home to seek thrills and easy money. He vows to find the Red Devil and discover why he is so merciful and so particular about his victims. Charlie trails Meg’s hoof prints to the hideout and forces Jimmie to switch roles – but the new Red Devil becomes addicted to the excitement of robbing and killing. When will retribution catch up with Charlie? Can anyone save him? And where is Jimmie Curry?
