Synopsis:
After Batman trapped Man-Bat in the Bat-Cave, he left to find Francine Lee. He hoped to use her to convince Langstrom to take the antidote which would cure him. When Batman and Francine return to the cave, Man-Bat is gone. Batman asks Francine to contact him if she finds him.

Later Man-Bat does contact Francine. Instead of convincing him to take the antidote, Francine agrees to be turned into a bat herself. Langstrom them recreates the formula which turned him into Man-Bat and uses it on Francine.

The two creatures then stage a wedding wearing rubber masks. Batman interrupts the wedding and exposes them. He then uses the antidote on both, changing them back into human form.
