Synopsis:
Bruce Wayne spots a wanted crook, Jo-Jo Gagan, on the street. He follows Gagan, but a nearby chemical explosion causes him to lose the trail. When he resumes the manhunt as Batman he finds Jo-Jo again, but discovers the chemical explosion has psychically linked him to the crook. When Jo-Jo is injured Batman feels an identical pain.

The underworld turns on Jo-Jo after learning about the connection. They believe if they kill Jo-Jo, Batman will die too. Jo-Jo also realizes this and escapes from them. Gagan also puts together the clues to learn Batman’s secret identity. He tries to give the information to the mob to get them off his back, but he dies before he can tell them. Batman has discovered an antidote to break the connection with Jo-Jo and lives even after Jo-Jo dies.
