Basic Plot Outline
Act I
In the winter of the year following The Dark Knight, Batman has become an outlaw in the eyes of Gotham city, working to stop crime and prevent his own capture at the same time. He has once again moved back to his Mansion on the outskirts of the city, and has erected a massive batcave, complete with his sonar tracking technology. In his duel life, Bruce has become a respected philanthropist, and is trying to pick up where Harvey left off. What Bruce doesn’t know is that Harvey is still very much alive, or dead, depending on how you look at it. Two-Face has indeed survived, and has gone underground, enlisting the aid of the many criminals he was tried to lock away. Eventually he takes the Maroni families remaining allies by force.
The next in line, a half wit name Anthony Zucco, is kicked out by Two-Face. Zucco turns to a life of selling phony insurance policies to get by. Eventually he approaches a travelling Circus and attempts to strong arm the owner into buying, but it doesn’t work. Out of desperation, he attempts to sabotage the equipment. That night, at the performance, with Bruce Wayne and Selina Kyle in attendance, the rope snaps and kills the flying Graysons, leaving their son without a father or mother. Dick was training to be their newest member. Bruce is very shaken by the event, but realizes that he cannot take care of the child, so he allows him to be placed in an orphanage. Zucco is caught by the police and taken into custody as well.
Later that night Batman meets anonymously with Gordon, Gordon passes along info on an escaped convict named “Waylan Jones” who he admits is a little too much for the cops to handle. Batman says he’ll trail him and see what he can do.
Meanwhile in Arkham, Harleen Quinzel eagerly awaits another session with her patient, the Joker. During a therapy session, Joker warns of an earthquake.
Batman finds himself trailing Waylan Jones throughout the sewer system. Eventually he finds him eating rancid meat with he has been storing for nourishment. Killer Croc, as he calls himself, ends up fighting with Batman. During the fight an earthquake rocks throughout the city, imprisoning both Batman and Killer Croc. Eventually Batman is able to hoist himself, and the unconscious Croc to the surface, but they find Gotham devestated. The Earthquake destroys all the bridges and tunnels, knocks the power and water out completely, leaving the city in chaos.
Ironically, throughout all of this, Wayne Manor survives basically unscathed.
A group of Gotham’s elite is gathered by Lucius Fox and the Mayor to determine how to quickly deal with this crisis, as the city descends into madness. On the otherside of this equation, Gordon doesn’t have the manpower to deal with the problem, and he convinces his forces to once again form an uneasy alliance with the Batman.
As if things couldn’t get worse Arkham is totally openned. Two-Face goes there with several gang members so he can use the freaks of Gotham to run the new Gotham of freaks. Joker refuses to leave, despite Harleen’s best efforts to convince him, saying he’d rather enjoy watching the outcome himself than being a part of it. Instead Harleen herself leaves, becoming a female Joker she names Harley Quin. With her joins the sickened Victor Frees and the murderous Ventriloquist.
Meanwhile, Bruce goes to inspect the remains of his Penthouse in Gotham, it is heavily damaged, but the sub-basement lair survived the earthquake, however it has been exposed. He and Alfred destroy the lair to cover up his connection to Batman. When they go to return to the mansion though, they find a young child attempting to steal the hubcaps off of Bruce Wayne’s car; it is Dick Grayson. Bruce realizes there is no way he can allow the boy to stay in this hellish nightmare while his home still has water, food, and electricity. Bruce takes him home.
Master Grayson is belligerent and hard to deal with, and Bruce’s life is now solely focused on saving Gotham. The boy frequently finds himself alone, or confined to certain areas on the grounds. Eventually he escapes.
Shortly after this, the Mayor is found murdered, and a note is stapled to his chest. The note is a document from IA, written by Harvey Dent, linking the Mayor to drug trafficking in Gotham City. Batman realizes Two-Face may still be alive. Gordon informs him that Zucco claimed Two-Face banished him from the mob weeks before his arrest. Zucco, however, escaped during the Earthquake.
Batman goes to find him. After a car chase with Zucco in the Batmobile through the tattered streets in Gotham, Zucco crashes in the remains of the Circus. Batman chases him throughout the Circus, but Zucco is eventually put down, by Dick Grayson, who knocks him out by swinging into him. Batman and Dick get into a verbal argument when Dick attempts to shot Zucco in the head with his own gun. Batman takes off his mask and reveals himself to be Bruce Wayne, telling Dick what happened to his parents. He tells Dick he’s not old enough to decide whether or not to “cross the line”, but Bruce says if he puts down the gun he’ll train him and when he is old enough he’ll let him finally decide who he will become: a hero or a villain.
Act II
Two-Face, Frees, Quin and the Ventriloquist break into Wayne Industries, taking Lucius, Mr. Reese and several others hostage. Two-face appoints himself Mayor and sets up a kangaroo court for all those who once led Gotham. The verdict is always determined by chance. Frees implores him to spare Lucius Fox, as they were once friends before his accident. Though he faces the court, Lucius Fox is granted life by a fortunate coin toss.
Lucius is horrified to see what has come to his friend Victor and even more horrified by the fact that he has become a killer, none the less, he allows him access to his tech. Victor confides in Lucius that his wife is dying of a unique disease and his research is what he is now. Victor is able to construct a liquid nitrogen gun and renames himself “Mr. Freeze”. Lucius promises that if Victor helps put an end to this madness, he’ll help him cure his wife, but Mr. Freeze says she is already dead.
Keeping the peace outside, Gordon begins to collapse under the strain. His forces have begun to fraction into those that support Two-face’s reign, and those who still wish to return Gotham back into what it was. Batman stays by Gordon’s side, although this seems to strain the ranks of the remaining police even more. Finally Batman tells Gordon his presence is doing more harm than good, and leaves Gordon.
As the power stays down, so do most of the cellphones, and Batman’s bat-sonar computer in his cave is rendered basically useless. He goes to Waynetower, but finds in ruins, forcing him to turn to good old fashioned detective work. As he searches the Applied Science division, which has been basically raided, he finds several files pulled on Victor Frees. Up in the board room, he discovers a list of names each labelled “innocent” or “guilty”, but the verdicts are random, as if they were determined by chance. There is one last name on the list that has not been tried: Bruce Wayne.
As he attempts to depart, The Ventriloquist shows up with several gang members and defecting police officers. The group has a standoff where Batman is forced to fight his way through. After a lengthily battle, Batman manages to disarm the henchmen and destroy Scarface. The Ventriloquist goes into shock. Batman is able to convince him to tell him where they are going.
Two-Face has made his way to Wayne Manor with Victor Frees, and Harleen Quin and Lucius Fox, Dick Grayson, and Alfred Pennyworth as the hostage. Gordon forms a permeter around Wayne Manor with his few remaining police forces, and Two-Face issues a statement to Gordon. That if Bruce Wayne doesn’t appear by 2 am, he will detonate charges he placed beneath Wayne Tower, forever descending Gotham into darkness and chaos. Batman agrees. Bruce shows up on his lawn by midnight and proceeds to turn himself over to Two-Face. After Harley Quin beats Bruce up with a baseball bat he is tied to a chair in his own living room. Dick starts to cheer as Harley beats up Bruce Wayne, saying he never liked the old guy anyways. Two-face believes the young child and allows him to join in. However, once Harley hands the bat to him he knocks her out with it.
Two-Face is enraged and holds a gun to Dick Grayson’s head. Lucius Fox turns to Frees, imploring him not to let such an atrocity go on. Frees hesitates as Harvey flips his coin, it lands scarred side up. Freeze shots as Harvey, hitting him in the chest, so Harvey shoots Freeze instead; killing him. This allows Lucius to escape. He cuts the lights in the mansion. Grayson unties Bruce and leads him to the elevator down to the cave. Two-face, however has captured Alfred, and makes him show him where Bruce went. Gordon witnessing the commotion from outside, goes in alone. He follows Two Face, who goes to the cave elevator, and they descend downward.
Two-Face appears in the cave as a maskless Batman stands alone watching. Two-face, of course, realizes who Batman is. Bruce tries to reason with Harvey and tell him he doesn’t have to do this. Harvey doesn’t listen though. He turns his gun on Alfred and flips his coin. Suddenly, Dick Grayson comes crashing down on top of Harvey before he can catch his coin. Alfred is freed. Two-face knocks Grayson against a wall, before he can turn his gun on the boy Batman tackles him.
The two end up in a battle of brawn and bullets. Smashing through Batman’s crime lab. Two-face grabs a batarang from the table and stabs Batman with it, causing him to fall backwards. Two face stands over him, aiming his gun at his head. A bullet nicks the top of Two-face’s skull, he falls. Gordon approaches, holding his gun. He gets Batman to his feet. Batman looks down at Harvey, who is still alive, despite the injury. He will be in comatose for the rest of his life. Gordon apologizes for Gotham taking Bruce’s parents and says his secret is safe. With Gordon, Lucius, Dick and Alfred, Batman finally has a complete family again.
The Mayor’s deputy steps in as Mayor, and with Lucius back at Wayne Tower power is successfully restored. As the lights flicker back on in Gotham, we see the silhouette of Batman step out onto a rooftop, he is shortly followed by Robin.
