Here is the official synopsis of The Dark Knight Rises below:
It has been eight years since Batman vanished into the night, turning, in that instant, from hero to fugitive. Assuming the blame for the death of D.A. Harvey Dent, the Dark Knight sacrificed everything for what he and Commissioner Gordon both hoped was the greater good. For a time the lie worked, as criminal activity in Gotham City was crushed under the weight of the anti-crime Dent Act.
But everything will change with the arrival of a cunning cat burglar with a mysterious agenda. Far more dangerous, however, is the emergence of Bane, a masked terrorist whose ruthless plans for Gotham drive Bruce out of his self-imposed exile. But even if he dons the cape and cowl again, Batman may be no match for Bane.
So, there you have it. The synopsis pretty much has a pending doom for Batman. As the TV spot #10 suggested by Catwoman, “You’re no match for these guys.” Batman really has his work cut out for him. As I would like to say when it comes to Batman sacrificing himself for the good of Gotham, “You reap what you sow.”
