The follow-up to the action hit "Batman Begins," "The Dark Knight" reunites director Christopher Nolan and star Christian Bale, who reprises the role of Batman/Bruce Wayne in his continuing war on crime. With the help of Lieutenant Jim Gordon and District Attorney Harvey Dent, Batman sets out to destroy organized crime in Gotham for good. The triumvirate proves to be effective, but they soon find themselves prey to a rising criminal mastermind known as the Joker, who thrusts Gotham into anarchy and forces the Dark Knight ever closer to crossing the fine line between hero and vigilante.
