While eavesdropping on a child pornography ring and awaiting police backup in
Gotham City, Jason Todd (Robin) ignores Batman's orders and attacks the criminals. Batman chastises Jason and asks if he considers crimefighting a game; Jason replies that life is a game. At
Wayne Manor, Batman decides Jason is emotionally unstable and relieves him of his duties as Robin; an enraged Jason storms off. Meanwhile, the Joker escapes from
Arkham Asylum. Batman discovers that he has obtained a nuclear weapon and plans to sell it to terrorists, and tracks him to
war-torn Lebanon. Walking through his old neighborhood, Jason meets a friend of his late parents, who gives him his father's old documents. Jason discovers that his mother's name on his
birth certificate is blotted out. Her first initial is "S", not "C" as in Catherine Todd, the woman he knew as his mother. Jason concludes that Catherine was his stepmother and decides to search for his biological mother. He uses the
Batcomputer to track three possible individuals to the Middle East and Africa. Jason travels to Lebanon, where he and Batman reunite. The two foil an attempt by terrorists to destroy
Tel Aviv using the nuclear missile purchased from the Joker. Batman agrees to help Jason find his mother, and Jason interrogates his first suspect,
Mossad agent Sharmin Rosen. His next suspect, Batman's old acquaintance
Lady Shiva, says she is not Jason's mother after she is administered a
truth serum by the duo. Batman and Jason travel to
Ethiopia and confirm that Jason's mother is Sheila Haywood, an aid worker; Jason has an emotional reunion with her. However, the Joker discovers that Sheila had performed illegal surgeries on teenagers in Gotham and has been blacklisted as a medical practitioner. He blackmails her into giving him the medical supplies her agency has stockpiled in a warehouse. He sells them on the black market and stocks the warehouse with
Joker venom, which will kill thousands of people. Jason witnesses the Joker blackmail Sheila, so he reveals his identity as Robin to her and offers to help. Sheila rebuffs him, as she has been embezzling from the aid agency; in an attempt to cover this up, she hands Jason over to the Joker. The Joker beats Jason with a
crowbar and restrains him and Sheila in the warehouse with a time bomb. Jason throws himself on the bomb to protect Sheila as the warehouse explodes. Batman arrives too late to save them, and Jason and Sheila die from their injuries. Traumatized, Batman takes Jason and Sheila's remains to Gotham and holds a burial with
Alfred Pennyworth,
Commissioner James Gordon, and
Barbara Gordon. Batman blames himself for Jason's death and resolves to carry on alone, rejecting Alfred's suggestion to involve Dick Grayson, the first Robin.
Ayatollah Khomeini approaches the Joker and offers him a role in the
Iranian government. The Joker leaves a warehouse containing the corpses of his henchmen and the address of the
UN Headquarters for Batman. As Batman waits outside the UN building, Superman appears and tries to convince Batman to leave. The Joker is
Iran's representative to the UN and will be giving a speech on the floor of the
General Assembly, and any confrontation between Batman and him could start a
diplomatic incident. During his speech, the Joker attempts to poison the chamber with Joker venom, but Superman intercepts it. Batman pursues the Joker onto a helicopter sent by his sponsors. During the resulting struggle, one of the Joker's henchmen opens fire with a machine gun and shoots the pilot, crashing the helicopter into the sea. Superman saves Batman, but the Joker disappears. Batman laments that everything between him and the Joker ends unresolved. ==Reception==
