Sometime after the Enchantress’ defeat, the Joker breaks up with Harley Quinn, throwing her out on the streets of Gotham City. She is taken in by Doc, the elderly owner of a Taiwanese restaurant, and recovers from her relationship by cutting her hair, adopting a spotted hyena (whom she names after Bruce Wayne), and taking up roller derby.
One night, Harley gets drunk at a nightclub owned by gangster Roman Sionis, and cripples Roman’s driver after he insults her. She then meets burlesque singer Dinah Lance, who later rescues an intoxicated Harley from an attempted abduction; that night, Harley blows up the Ace Chemicals plant where she pledged herself to the Joker years prior as a way to publicly announce their breakup. Spotting the scuffle from his bedroom, Roman is impressed by Dinah’s skills and appoints her as his new driver. Meanwhile, GCPD Detective Renee Montoya investigates a series of mob killings carried out by a crossbow-wielding vigilante. Finding Harley’s necklace at the scene of the Ace Chemicals explosion, Montoya notes that Harley is in danger without the Joker’s protection. She approaches Dinah about being an informant on Roman for them, but Dinah rejects the offer.
