Jeffery Fairchild is a wealthy and aloof playboy who built a hospital with his family fortune. Dr. Skull is an elderly inner-city doctor who helps the underprivileged. The Skull Killer is a mentally imbalanced vigilante. All three are the same man.
Jeffery Fairchild is not right in the head; but his city, filled with real-life monsters is even more disturbed. Is Jeffery crazy? Is he pharmaceutically altered? Or is his city just that messed up? The Skull Killer (and for that matter, Jeffery) is not a hero. He is a crazy man in a crazy world where monsters and insanity rule the day.
