Plot summary
Gotham's citizens become nervous when Joker suddenly decides to become the "Batman", going after anyone for their crimes no matter how trivial it is, and charging the city for his services. Batman, seeking to stop this, finds himself attacked by Joker, who injects him with Joker venom. Bruce, who begins to transform into a new Joker, finds he must recover Joker's venom to create an antidote, though the matter becomes complicated when Penguin commits a bank heist that draws in Joker's attention, leading to a threeway bout between them and Batman.
