Ra's al Ghul hires the
Joker as a distraction so that Ra's could destroy
Europe's financial districts. He realizes his mistake when he is unable to control the Joker, who captures
Jason Todd, the second
Robin and
Batman's partner. In
Sarajevo,
Bosnia, Joker brutally assaults and tortures Jason in an abandoned warehouse with a crowbar. Joker eventually leaves and locks Jason inside the warehouse with a bomb, which explodes and kills Jason before Batman arrives. Five years later in
Gotham City, a mysterious vigilante called
Red Hood assembles a meeting of the city's most prominent drug dealers. He announces a takeover of their drug trade, taking 40 percent of their profit while offering them protection from
Black Mask and Batman, but threatens to kill them if anyone is caught dealing drugs to children. Batman stops an attempted theft of a shipment that belonged to Black Mask, which contains the advanced android
Amazo. Batman destroys Amazo with the help of Jason's predecessor
Dick Grayson, using the name
Nightwing, and discovers the thieves are working for Red Hood. The thieves are killed by a sniper shot before they can reveal any more. Batman identifies the shooter as the Red Hood, and chases him to
Ace Chemicals. The Red Hood references the creation of the Joker in this same building before blowing up the facility. Batman and Nightwing interrogate Joker at
Arkham Asylum about Red Hood, but he denies any involvement. An infuriated Black Mask puts a hit on Red Hood for Amazo's destruction. Batman and Nightwing prevent Red Hood from hijacking Black Mask's next weapon shipment. They chase Red Hood to a train station, where he escapes after detonating a bomb, which injures Nightwing. As
Alfred Pennyworth tends to Nightwing, Batman realizes that the Red Hood is trained and has knowledge of Batman's tactics, gear and his secret identity. Batman recalls Jason performing the same maneuvers as Robin and that Jason grew more violent as he aged. Black Mask sends the Fearsome Hand of Four to lure Red Hood. They nearly overpower him until Batman helps incapacitate three of them and Red Hood kills the fourth, horrifying Batman. Red Hood explains that he is doing what Batman will not: killing criminals who are not afraid. Batman analyzes a blood sample of Red Hood drawn from the battle and it matches to Jason. After discovering that Jason's corpse is fake, Batman confronts Ra's al Ghul and demands to know the truth. Ra's explains that he felt responsible for Jason's death and, as a peace offering, swapped Jason's body for a fake and revived him in the Lazarus Pit, but following his resurrection, Jason was driven insane and escaped. After surviving an assassination attempt by Red Hood, Black Mask sets the Joker free, tasking him with killing Red Hood. However, The Joker instead abducts Black Mask and the drug dealers and plans to set them on fire. Red Hood appears and reveals his real target is the Joker. Batman saves the hostages and Red Hood takes Joker. Red Hood brutally beats Joker in revenge and confronts Batman. Batman and Red Hood fight and Red Hood reveals himself as Jason. Their fight makes its way to the dilapidated building, where Jason is keeping the Joker and ends with Jason holding Batman at gunpoint. Though having forgiven Batman for not saving him, Jason is upset and angry that Joker is still alive after killing him. Batman admits that he has thought constantly about torturing and killing the Joker but will not, fearing he will not stop if he kills even once. Jason tosses Batman a gun and gives him an ultimatum – he will execute the Joker unless Batman shoots him. Batman refuses and drops the gun, causing Jason to shoot at Batman. Batman dodges the bullet, throws a
Batarang, which jams and destroys Jason's pistol. Jason sets off a time bomb and Batman subdues Joker before attempting to save Jason. The bomb explodes; Batman and Joker survive, but Jason is gone. Joker is returned to Arkham and Black Mask is arrested. At the Batcave, Alfred offers to remove the glass case display of Jason's Robin costume, but Bruce refuses, claiming it does not change anything. A final flashback shows Jason's first day as Robin, which he cheerfully declares is the best day of his life. ==Cast==
