In Gotham City, the Joker robs a mob bank with his accomplices, whom he tricks into killing one another, ultimately killing the last one himself. While investigating the robbery, Batman and Lieutenant James Gordon contemplate including new district attorney, Harvey Dent, in their plan to eradicate the mob. Batman, however, wonders if Dent can be trusted. Wayne runs into Rachel Dawes and Dent, who are dating, and after talking to Dent, he realizes Dent's sincerity and decides to host a fundraiser for him. Mob bosses Sal Maroni, Gambol, and the Chechen meet with other underworld gangsters to discuss both Batman and Dent, who have been cracking down on the mobster's operations. Lau, a Chinese mafia accountant, informs them that he has hidden their money and fled to Hong Kong in an attempt to preempt Gordon's plan to seize the mobsters' funds and hide from Dent's jurisdiction. The Joker appears and offers to kill Batman for half of the mafia's money, but they flatly refuse and Gambol places a bounty on the Joker's head. Not long after, the Joker kills Gambol and takes control of his men.
