Catwoman is released from prison, and claiming she wants to enrich her education, enrolls at Gotham City University. She dresses one of her own henchmen as the Caped Crusader in order to frame him for a robbery. With Batman in jail, she goes ahead with her plan for a mass sit-in at Chimes Square. Catwoman is more than surprised when Batman himself shows up at the event. However, his efforts to expose the villainess are futile, and she prepares to terminate him and Robin in front of the whole crowd.

Catwoman goes ahead with her scheme to steal several Batagonian Cat's Eye opals, but she has trouble finding someone to fence them since such rare stones would be easily spotted. With little recourse left, she decides to turn them in for the reward money. It seems like the perfect job for her acquaintance, Freddy the Fence. But when he notices that the gems are fakes, Catwoman realizes she has been tricked by Batman and vows to get revenge on the Caped Crusader once and for all.
