As an 8-year-old boy, Bruce Wayne (GUS LEWIS) seemed to have everything -- family riches beyond belief and a pair of loving parents in Thomas (LINUS ROACHE) and Martha (SARA STEWART) who didn't mind that their son was now terrified of bats following an accidental encounter with a swarm of them. Another unexpected incident, however, left Bruce orphaned. Although he was cared for and raised by the family butler, Alfred (MICHAEL CAINE), and had access to a seemingly endless supply of money, his parents' murders left a stain on his psyche that he can't shake.
Now, years later, Bruce's home city of Gotham is overrun by corruption ranging from bad cops such as Flass (MARK BOONE JUNIOR), to crime lord Carmine Falcone (TOM WILKINSON) and his mental practitioner crony Dr. Jonathan Crane (CILLIAN MURPHY) who gets criminals off on insanity pleas when not planning his own scheme to deal the city another serious blow.
After Falcone informs Bruce (CHRISTIAN BALE) that he could never understand the criminal world, the young man sets out to figure out the ways of the criminal mind, and gets himself thrown into a remote Asian prison. It's there that he draws the attention of Ra's Al Ghul (KEN WATANABE) and his front man Ducard (LIAM NEESON) who sense potential in Bruce and then train him to join their League of Shadows. It's an age-old, secret organization that rids the world of corruption and decadence. Having taken down the likes of Constantinople and Rome eons ago, they've now set their sights on Gotham.
Wanting justice rather than revenge, Bruce breaks free from them and returns to Gotham, desirous of cleaning up the place. With the aid of Alfred and Lucius Fox (MORGAN FREEMAN) from his own company's Applied Sciences division, Bruce sets out to turn himself into a superhero of sorts. To Rachel Dawes (KATIE HOLMES) -- his childhood friend who's grown up into the assistant DA -- he's just a billionaire playboy without a care in the world, and for Mr. Earle (RUTGER HAUER) who now runs Wayne Enterprises, he's an inconvenience, albeit a manageable one.
In the guise of Batman, however, he's a mysterious vigilante to Flass' honest cop partner Jim Gordon (GARY OLDMAN), and the worst nightmare to the likes of Falcone and others. Yet, as a mysterious figure known as The Scarecrow begins to make his move on the city with his powerful, hallucinogenic drug, Bruce must use every resource in his repertoire to save the day and the residents of Gotham.
