The full plot runs from a midair kidnapping to a bomb carried out over the bay, and it turns on a reveal about who has been running the plan. Bane, a former League of Shadows member, kidnaps a nuclear physicist in a midair raid. Gotham seems peaceful, but it rests on the hidden lie about Harvey Dent.
Bruce Wayne, withdrawn and physically worn down, is drawn out by Selina Kyle's theft of his fingerprints. Bane works with the businessman John Daggett to take over Wayne Enterprises, and he uses the stolen prints to wipe out Bruce's fortune. Selina then lures Batman into a trap, and Bane breaks him and drops him into a remote underground prison.
With Batman out of the way, Bane cuts Gotham off from the world. He traps most of the police underground and turns a Wayne fusion reactor into a bomb. The wealthy are put before mock courts, and prisoners are released from Blackgate, so the city is run by fear rather than by law.
Months later Bruce heals, climbs out of the prison, and returns to Gotham as Batman to free the police. Miranda Tate is revealed to be Talia al Ghul, the daughter of Ra's al Ghul, and she is the true mastermind. Bane is killed with Selina's help, and Talia tries to make sure the reactor cannot be stopped.
Batman uses his aircraft to carry the bomb out over the bay, where it detonates far from the city. Bruce is believed dead and Gotham honors Batman as a hero. His will turns the manor into an orphanage and leaves his legacy to others, while Alfred glimpses Bruce alive abroad with Selina. Young officer John Blake, whose legal first name is Robin, is led to the Batcave.
