Premise
When the mysterious Arkham Knight emerges to establish a new order in Gotham and Arkham through iron fist, Batman and Deadshot must bring together a team with their allies to end their new enemy's tyranny.

Plot
In the docks of Gotham City, Batman intercepts Amanda Waller and her Task Force X Squad (consisting of Captain Boomerang, Killer Croc, Harley Quinn, Black Manta and their new leader Bane), who were on a mission to assassinate Black Mask and is gang and retrieve the weapons they stole. When a fight ensues, Deadshot also arrives and joins Batman's side as they destroy the weapons and apprehend Black Mask, foiling the Squad's mission. Just then, they are confronted by a pack of mercenaries led by a new vigilante with a militarized version Batman's armor calling himself the Arkham Knight. Batman and Deadshot are overwhelmed by the Arkham Knight, but they manage to survive an explosion caused by him in the docks while the Arkham Knight's soldiers apprehend Waller and her Squad and kill Black Mask as Arkham Knight voices his goal to establish a new order on Gotham City and Arkham Asylum.

A couple days later, the Arkham Knight's forces had managed to enslave most of the inmates of Arkham Asylum and took control of ARGUS as their leader is determined to eliminate Gotham's criminal underworld on a manner Batman swore to never follow. Little does the Arkham Knight know that Batman and Deadshot had convinced most members of the Gotham City Police Department, including Commissioner James Gordon, in forming a Resistance against the Arkham Knight's empire with Gotham's high-ranking reporter Vicki Vale acing as the vigilante hacker Oracle.

Vicki also manages to recruit most of Batman's close allies to join the Resistance, including the Bat-Family (Batwing, Batwoman, Nightwing, Robin and Gordon's daughter Barbara, who joined the family as Batgirl), Justice League members (consisting of Flash, Cyborg and new comers Green Arrow and Black Canary) and Raven. The heroes split up in multiple areas protecting the citizens and freeing all they can from the eyes of Arkham Knight's mercenaries.

Deducing that the Arkham Knight's forces control the city through high tech drones programmed to hunt down and kill rebelling world leaders and nuke the city, Batman and his teammates hunt and defuse the drones one by one. With the last drone defused, the Resistance members (with Raven's help) shelter the Resistance into a safe place and set out to battle the Arkham Knight's forces. On the middle of the chaos, Batman confronts the Arkham Knight himself, who reprimands Batman for "being so weak" when he chose to spare criminals rather than execute them.

Just as Commissioner Gordon arrives, the Arkham Knight reveals himself to Gordon's horror as his son James Gordon Jr., who was dissatisfied with the superheroes' no-killing policy and decided to take over the discontinued protocols to the U.S.A. army and the League of Assassins to begin a crime-hunting crusade of his own. After a brief fight, J.J. vanishes. Deadshot, Nightwing, Robin and Green Arrow set out to implant explosives in the Arkham Knight's weapon facility before they are attacked by the Joker and his gang as the Joker decided that he should let the Arkham Knight take control so that he and Batman may kill each other "like animals".

Just then, under Bane's orders, the Arkham Knight's soldiers attack and fire at both groups. Joker and his henchmen are shot dead, but the others survive and Deadshot is successful in detonating the bomb, destroying the arsenal while Vicki (thanks to a microchip implanted on the core of Arkham Knight's central computer by Batgirl) hacks the ARGUS tech and defuses the bombs implanted on the Suicide Squad members' necks. While the others retreat, only Bane remains loyal to the Arkham Knight and resumes to fight the Resistance until Nightwing and Cyborg defeat him.

After they neutralize the remaining militia, Batman and Deadshot face the Arkham Knight for one final showdown. Just as Batgirl (who had learned of the Arkham Knight's identity from her father) arrives and unmasks herself in front of him, the Arkham Knight, understanding the tyrannical monster he had become (not just for the criminals, but for his family as well), finally relinquishes his armor and equipment and surrenders. The remaining members of the militia and the Squad turn themselves in as James is sentence to prison in Belle Reve alongside Waller, who was exposed for her own involvement with the Suicide Squad members, whose existence is now public knowledge.

Barbara is comforted by Bruce and Zoe over James's condition as Alfred remarks to Floyd and Damian that despite James' madness, he was still her brother. As Batman and the others resume their roles in Gotham City, two delinquents fight over a stolen handbag in Crime Alley in the presence of a girl nearby before they are shot dead by Red Hood.
