Dark, complex, and unforgettable, The Dark Knight succeeds not just as an entertaining comic-book film, but also as a richly thrilling crime saga. With the help of allies, Batman (Christian Bale) is able to keep a tight lid on crime in Gotham City. But when a young criminal calling himself the Joker (Oscar winner Heath Ledger) suddenly throws the town into chaos, the caped crusader begins to tread a fine line between heroism and vigilantism.
