Synopsis:
Batman rescues heiress Heloise Madigan from thugs trying to kill her. When he takes her back home, the family lawyer explains that she is not the real Heloise. Her real identity is Colleen Kiernan, the former secretary for John Madigan.

Batman then prevents the murder of the real Heloise before realizing that Colleen is the actual target. He follows Colleen to the office of Kenneth Rogers and stops the real estate tycoon from killing her. Colleen had been blackmailing Rogers with information she learned as Madigan's secretary. Batman then delivers Rogers and Kiernan to the police.
