With the help of Lieutenant Jim Gordon (Gary Oldman) and the committed new District Attorney, Harvey Dent (Aaron Eckhart), Batman (Christian Bale) sets out to destroy organized crime in Gotham City for good. The triumvirate initially proves to be effective, but they soon find themselves prey to a rising criminal mastermind known as The Joker (Heath Ledger), who thrusts Gotham into anarchy and forces The Dark Knight ever closer to crossing
the fine line between hero and vigilante.
