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. However, Batman
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.
In Hong Kong, Batman captures Lau using a skyhook, and delivers him to the
Gotham City police, where Lau agrees to testify against the mob. Dent and
Gordon arrest the mob, and in retaliation the Joker issues an ultimatum to
Gotham: people will die each day until Batman reveals his identity. When
Commissioner Gillian B. Loeb and the judge presiding over the mob trials
are killed, the public readily blames Batman, prompting Wayne to decide to
reveal his identity. Before Bruce can turn himself in, Dent holds a press
conference to try and persuade the public not to sell Batman out just
because of one terrorist. However the public, though grateful for
everything Batman has done for the city, insists that things have now
reached a point where Batman must make the sacrifice, so Dent announces
that he himself is Batman and is arrested as part of a plan to draw the
Joker out of hiding. The Joker attempts to ambush the police convoy
carrying Dent, but Batman and Gordon intervene and capture him. In
recognition of his actions, Gordon is appointed the new police
commissioner.
Later that night, Dent and Dawes disappear. At the police station, Batman
interrogates the Joker, who reveals that Dent's and Dawes' police escorts
were corrupt and have placed them in warehouses rigged with explosives on
opposite sides of the city—far enough apart so they could not both be
saved. Batman leaves to save Dawes, while Gordon and the police head after
Dent. With the aid of a smuggled bomb, the Joker escapes police custody
with Lau. Batman arrives, but finds Dent instead of Dawes. Batman
successfully saves Dent, but the ensuing explosion disfigures Dent's face.
Gordon arrives at Dawes' location too late, and she perishes when the bomb
detonates. Unable to cope with this new level of chaos, Maroni goes to
Gordon and offers him the Joker's location. Aboard a cargo ship, the Joker
burns Lau to death atop a pile of half the mob's money, and has the
Chechen killed before taking control of his men.
Meanwhile, an M&A lawyer working as a consultant to Wayne Enterprises,
Coleman Reese, finds out Batman's identity and after failing to blackmail
the company, decides to go public. However, realizing that he does what he
does only because of Batman, the Joker changes his mind about revealing
Batman's identity and issues a public ultimatum: either Reese is killed
within the hour, or he will blow up a hospital. When attempts on Reese's
life are foiled, the Joker goes to the evacuated hospital, disguised as a
nurse, and frees Dent from his restraints, convincing him to exact revenge
on the people whose corruption led to Dawes' death. Dent begins by
flipping a coin to decide if he should kill the Joker, and spares him. The
Joker destroys the hospital on his way out, and then escapes with a
hijacked bus full of hospital patients.
Out of the hospital, Dent goes on a personal vendetta, confronting Maroni
and the corrupt cops one by one and flipping his coin to decide their
fates. Now with complete control over the Gotham mob, the Joker announces
to the public that anyone left in Gotham at nightfall will be subject to
his rule. With the bridges and tunnels out of the city closed due to a
warning by the Joker, authorities begin evacuating people by ferry. The
Joker has explosives placed on two of the ferries—one ferry with convicts,
who were evacuated in an effort to keep the Joker from freeing them, and
the other with civilians—telling the passengers the only way to save
themselves is to trigger the explosives on the other ferry; otherwise, he
will destroy both at midnight. Batman locates the Joker and the hostages
he has taken. Realizing the Joker has disguised the hostages as his own
men, Batman is forced to attack both Gordon's SWAT team and the Joker's
henchmen to save the real hostages.
The Joker's plan to destroy the ferries fails after the passengers on both
decide not to destroy each other. Batman finds the Joker, and after a
brief fight, is able to subdue him, preventing him from destroying both
ferries. When Batman refuses to kill the Joker, the Joker acknowledges
that Batman is truly incorruptible, but that Dent was not, and that he has
unleashed Dent upon the city. Leaving the Joker for the SWAT team, Batman
searches for Dent. At the remains of the building where Dawes died, Batman
finds Dent holding Gordon and his family at gunpoint. Dent judges the
innocence of Batman, himself, and Gordon's son through three coin tosses.
As the result of the first two flips, he shoots Batman in the abdomen and
spares himself. Before Dent can determine the boy's fate, Batman, who was
wearing body armor, tackles him over the side of the building. Gordon's
son is saved, but Dent and Batman fall to the ground below resulting in
Dent's death. Knowing that the citizens of Gotham will lose hope and all
morale if Dent's rampage becomes public news, Batman convinces Gordon to
hold him responsible for the murders. Images are shown of Gordon
delivering the eulogy at Dent's funeral and smashing the Bat-Signal.
Police swarm the building, and Batman flees as Gordon and his son watch. |
