Once again, Daniel "Chaingang" Bunkowski is on the loose. After a seemingly endless term in prison, he is hungrier then ever to get his teeth into some bloody violence. The opportunities for mayhem were pretty limited in the maximum-security prison where he was being held for so long. Now that he's out, his keeper, Dr. Norman, is anxious to put him to work. He has given Chaingang an important task: hunt down and destroy the one man who is more savage than himself. Doc Royal has been living quietly in rural Missouri, successfully hiding his secret youth as a death-loving nazi. However, his past is about to come and haunt his present, just when Chaingang arrives to distract him from his troubles . . .
