Not sure exactly when you got cut off, but IIRC (might be small mistakes or omissions): [spoiler]Talia reveals herself as Ra’s al Ghul’s daughter. She was the “child” in the pit prison, and Bane was her protector. After she escaped, she came back with her father but Bane had been severely injured before they got there. Ra’s initially took Bane into the League of Shadows, but then kicked him out because he was such a horrible reminder of what happened to his wife and daughter.
So Talia tries to remotely detonate the nuke (with still about 11 minutes left on the countdown timer), but Gordon had managed to get aboard the truck with the nuke and attack the signal-blocking device. Talia gets in one of the camo-painted tank vehicles (can’t remember the name) and goes to intercept the truck to ensure they can’t reinsert the nuke into the fusion power plant and disarm it. She leaves Batman with Bane, and says she won’t kill him right now because she wants him to burn when the nuke goes off and destroys his city. As soon as she leaves, Bane decides he wants to kill Batman himself. It’s not looking good for Batman, when all of a sudden Bane gets blown away (literally blown across the room) - by Catwoman who has returned on the Batcycle having evidently decided not to get of the city as fast as possible.
There’s a car/tank chase scene, with the tanks firing missiles at the Bat vehicle/copter. Talia manages to climb from one of the tanks into the truck carrying the nuke. Eventually the three bad guy tanks get taken out one by one. The truck carrying the nuke crashes and Talia is mortally wounded. In her dying speech she reveals that she has activated the flooding system for the facility under the river where the fusion plant is (intercut to Lucius Fox narrowly escaping the flooding room by climbing a ladder). So even though they have the nuke, they will be unable to reinsert it into the reactor, and her father’s plan to destroy Gotham will be fulfilled.
During this last little while, those scenes are intercut with Blake getting all the boys from the orphanage/boys home onto a school bus and trying to get them and a bunch of other city residents across the last intact bridge out of town. But the soldiers stationed on the bridge to prevent people from escaping won’t let them leave, since they’re convinced that will cause Bane to detonate the nuke. Blake tries to explain that the nuke’s gonna go off anyways, but they won’t listen. They fire warning shots at his feet, then they blow demolition charges and take out a small section of the bridge to ensure no one can leave.
So now Batman/Catwoman/Commissioner Gordon have the nuke but there’s only four or five minutes left before it blows. Batman hooks it up to the winch on the Bat and decides to fly it offshore. He says he has to fly it himself since there’s no autopilot. Catwoman kisses him. Commissioner Gordon asks who he is, and says people should know who their savior is. Batman won’t give his name, and says that it’s better that Gotham doesn’t know who he is and that he’s just Batman. But then he tells how he remembers a time when a policeman put a jacket on a little boy’s shoulders and comforted him (I can’t remember the line exactly). As Batman takes off, Gordon flashes back to the memory of him comforting the young Bruce Wayne after his parents were killed. He incredulously realizes that Batman is Bruce Wayne. The Bat flies away from the city over the ocean into the foggy distance with the sound of stirring music. The little kids in the bus on the bridge are like “Hey! That’s Batman!” Blake looks wistful. The Bat flies out of sight and the nuke goes off with a bright flash and a mushroom cloud far out over the ocean.
Cut to Commissioner Gordon doing a reading at Bruce Wayne’s funeral on the small family plot (him and his parents tombstones) just outside Wayne Manor. The only other people at the funeral are Alfred and Blake.
Cut to a lawyer reading Bruce Wayne’s will. He had very little money left, but he bequeaths his house and grounds to the city as long as they never tear it down or alter it in any way, and they use it as an orphanage/boys home. The rest of his estate was left to Alfred.
Cut to Blake going somewhere to pick something up (I can’t remember what - maybe paperwork?) but there’s nothing there under John Blake. He says that maybe it’s under his full legal name, and gives them his ID. The lady says she likes his name, and maybe he should start going by Robin instead of John.
Cut to Blake talking to Commissioner Gordon. Gordon asks if he will reconsider resigning from the force, but he says he can’t stay any longer.
*Cut to *Blake putting on climbing gear and going through the waterfall into the Batcave - cut to Lucius Fox talking to R&D guys about how the Bat didn’t have an autopilot, and they say that it does and that Bruce Wayne did a patch and fixed it six months ago - cut to Alfred going to that cafe he used to go to on vacation, and he looks up and sees Bruce looking happy and relaxed and casual and sitting with Selena Kyle, then Bruce catches Alfred’s eye and nods - cut to Blake walking into the Batcave and some of the machinery activating - roll credits.
