When the menace known as the Joker wreaks havoc and chaos on the people of Gotham, Batman must accept one of the greatest psychological and physical tests of his ability to fight injustice.
The film takes place in Gotham City some time after the events of Batman Begins. A gang of masked criminals robs a bank run by Gotham's mob. One by one, the criminals betray each other until only one remains, revealing himself to be the Joker (Heath Ledger), and he escapes with the cash.
Directed by Christopher Nolan, “The Dark Knight” interrogates what it really means to be a hero, how people become villains and how to determine the right choice in complicated circumstances — even when it means going against personal interests. It's the second movie in Nolan's Batman trilogy.
