The story of the Dark Knight starts with the clown leading his men to rob a bank of a gang. The men are played by the clown's tricks and start killing each other. In the end, the clown still controls the whole situation and gets all the money. Some Batman’s supporters impersonated Batman and tried to help Batman hinder the drug trade between the gangster and the Scarecrow. At this time, Batman really showed up, and then he was injured in the battle because the armor was too heavy. He wanted to redesign the bat armor. Batman Bruce Wayne, Police Inspector Jim Gordon, and the new Attorney General Harvey Dante plan to wipe out the gang, so that Harvey can become a public hero in Gotham City, not just like Batman. Going incognito, Bruce discovers that Rachel is dating Dante.
The leaders of the Gotham City gang held a meeting to discuss how to deal with Batman, Gordon and Dante. Mr. Liu, the Chinese gang accountant, told the gang boss that he was the first to move the money from the underworld before the execution of the black money seizure plan planned by Dante. To Hong Kong. The clown suddenly appeared and proposed to hire him to kill Batman with half of the black money, but the gang refused, so the clown began to infiltrate the gang and control some of the gang's men.
When Batman successfully caught Liu who had fled back to Hong Kong and transferred it to Gordon, the gang had to agree to hire a clown to kill Batman. After the Joker accepted the employment, he used a Batman imitator to announce to the whole of Gotham City that as long as Batman does not surrender, someone will die every day thereafter.
Then the clown assassinated the police chief and the court judge one after another. When the clown killed the fifth person, Bruce couldn't bear to let the clown kill the innocent again and decided to surrender. But before he surrendered, Dante first declared that he was Batman, hoping to induce the Joker. The clown is in the middle of the game and appears to hijack the truck that escorted Dante, but is stopped by Gordon and Batman and arrested.
Batman began to interrogate the Joker. The Joker revealed that Rachel and Dante had been taken to both ends of the city and placed two remote-controlled bombs. The distance between them made Batman unable to rescue them at the same time. Batman immediately set off to rescue Rachel, while Gordon and the police went to rescue Dante. But the clown deliberately contradicted the positions of Rachel and Dante, so that the two of them were saving the opposite.
Through the cover of the bomb, the clown and Mr. Liu successfully escaped from the police station. Batman rescued Dante in time, but Dante was taken to the hospital with his left half of his face burned off by the fire. Gordon was not faster than Batman, failed to save Rachel, and killed her in the explosion. Dante went mad because of Rachel's death. At this time, the clown came to the hospital to release Dante and convinced him that he must avenge the police, gangsters, Gordon, and Batman. Dante became a double-faced man.
When Harvey questioned and used coins to decide the lives and deaths of the police and gang members, the clown burned half of the money from the gang with Mr. Liu, and once again announced to everyone that he would rule the streets. The citizens staying in Gotham City When night comes, he will rule. Bridges and tunnels were blocked by the clown’s bomb threat, and the government began to evacuate people by ferry. But the clown had previously planted bombs on two ferries, one carrying ordinary people and the other carrying prisoners, and told the passengers on both sides that the way to save himself was to use the detonator he prepared to detonate the other ship. Otherwise, both ships will be blown up remotely at midnight. Batman locked the position of the Joker and prevented him from blowing up the ship. After the Joker is defeated, he understands that Batman cannot be corrupted, but Dante is not.
So the Joker released his last card-he has released Dante's anger. Batman discovers that Dante has kidnapped Gordon and his family and brought them to the wreckage of the building where Rachel died. Dante began to toss a coin to decide the life and death of himself, Batman, and Gordon's son. Dante shot Batman in the abdomen. Just before Dante decided the little boy’s life or death, Batman threw Dante down, and both fell from the building at the same time, and Dante died on the ground.
Batman and Gordon know that if Harvey's murder of the police and other five people spreads out, the city will be chaotic and morally degraded, and this is the biggest purpose of the Joker. Batman persuaded Gordon, Batman to take these charges himself, in order to maintain Harvey's heroic image.
At the end of the film, Gordon had to issue a hunt for Batman, smashed the bat signal light, and gave Batman the title of Dark Knight.
