Hellblazer

John Constantine has lost his freedom and must adapt to life behind bars. Sentenced to a maximum-security penitentiary, the Hellblazer soon learns that there is a whole different set of rules to live and die by within the prison walls. But for a man that is used to making the rules, Constantine quickly realizes that to become king of this castle he will have to fight his way up the ladder through ruthless gangs, brutal guards, and finally to the prison's overlord. Then it will be time for everyone to learn his rules.
