"Enter Batgirl, Exit Penguin"
Barbara Gordon returns from college and has a date with Bruce, but is kidnapped by Penguin on her way home. Penguin threatens to kill her father if she doesn't agree to marry him, hoping to get criminal immunity if he's related to the Police Commissioner.
Penguin sends his men out to kidnap a minister to perform the ceremony, but they get Alfred instead. Barbara then slips out and changes into Batgirl, revealing her secret identity to Alfred. Batman and Robin find Penguin, but he knocks them out with umbrella gas. Batgirl follows and rescues everyone, then makes Alfred swear to keep her identity a secret.
Alfred gets in on a Bat-fight and dukes it out with Penguin.
