The Dark Knight is a 2008 superhero crime thriller film directed and co-written by Christopher Nolan. Based on the DC Comics character Batman, the film is part of Nolan's Batman film series and a sequel to 2005's Batman Begins.
Batman raises the stakes in his bourgeois war on crime. With the help of Lieutenant Jim Gordon and District Attorney Harvey Dent, Batman sets out to dismantle the remaining criminal organizations that plague the city streets.
The partnership proves to be effective, but they soon find themselves prey to a reign of chaos unleashed by a rising criminal mastermind known to the terrified citizens of Gotham as The Joker.
Set within a year after the events of Batman Begins, Batman, Lieutenant James Gordon, and new district attorney Harvey Dent successfully begin to round up the criminals that plague Gotham City until a mysterious and sadistic criminal mastermind known only as the Joker appears in Gotham, creating a new wave of chaos.
Batman's struggle against the Joker becomes deeply personal, forcing him to "confront everything he believes" and improve his technology to stop him. A love triangle develops between Bruce Wayne, Dent and Rachel Dawes.
With just one year having passed after taking out Ra's Al Ghul's plan to have Gotham eliminated and the mysterious disappearance of Dr. Jonathan Crane AKA the Scarecrow, and after the city was nearly plundered with his toxins, Bruce Wayne and his vigilante alter-ego the Batman, continue the seemingly endless effort to bring order to Gotham, with the help of Lt.
James Gordon and newly appointed District Attorney Harvey Dent. But a new threat has now emerged into the streets. The Dark Knight faces a rising psychopathic criminal called The Joker, whose eerie grin, laughter, and inhuman morality makes him as dangerous than what he has yet to unleash.
It becomes an agenda to Batman to stop the mysterious Joker at all costs, knowing that both of them are in an opposite line. One has no method at all and seeks to see the world plunge into the fire he has yet to light. One represents the symbol of hope and uses his own shadow to bring the peace and order he has yet to accomplish doing.
