After more than a year of training under Batman, Barbara Gordon has mastered her abilities and established herself as Batman's crime-fighting partner, Batgirl, though she still struggles to adapt into her new role. While she and Batman escort a police transport carrying prisoners to the rebuilt Arkham Asylum, Batgirl accidentally releases several inmates, including Solomon Grundy. While trying to stop Grundy's rampage through the city, Batman is knocked unconscious. Batgirl intervenes to protect him and defeats Grundy. Leaving Grundy in Innovative Concepts' custody, Batman informs Batgirl that he will be going to Louisianna for a few weeks to assist Vicki Vale as she does her story on the Task Force X, and entrusts Batgirl to look after Gotham in his absence as its sole dark knight. Later, Batgirl investigates a break-in at Innovative Plaza and stops the Enigma from stealing Innovative's new experimental power source.
