Jack is a clerk of a big automobile company and a man full of middle-aged crisis consciousness. He hates his life and everything around him very much. In addition, he suffers from severe insomnia, so he has a whim to treat himself. , Decided to participate in the group consultation meeting. Jack first participated in a mutual comfort group for terminally ill patients. He came into contact with a group composed entirely of people suffering from testicular cancer. Jack comforted and cried with them, and became addicted.
One day, Jack meets Taylor, a soap merchant. He is a rogue hero full of rebellious, cruel and violent action. As soon as they met, Taylor made a strange request to Jack. He wanted Jack to beat himself up. In the rally, Jack realized the joy of fighting, and the two became friends by chance. They began to create a "fighting club": an organization that allows people to fight with their hands without wearing protective gear, with the purpose of venting their emotions. The club has established a series of activity rules: it is forbidden to talk about the club to others, only two people are allowed to fight and so on.
The underground club began to attract more and more people, and gradually developed into a national underground organization, all members regarded Taylor as the godfather. Taylor attracts those who follow blindly with his own personality magic and philosophy of action. He becomes more and more extreme. He makes members fight everywhere, destroy everywhere, smash cars, set fires, and urinate in the food of customers. The behavior is getting crazy.
Jack became more and more unbearable about the current situation of the "fight club" and Taylor's behavior. At the same time, he was surprised to find that Taylor had also organized an army, and he wanted to take greater revenge against the society. Jack decides to alienate Taylor, but to his surprise, wherever he goes, he is considered Taylor and revered as the godfather. This gave Jack a big blow, and he began to reflect on who he was and who Taylor was. In the end, he was horrified to discover that he was "Taylor", Taylor was the other side of "I" humanity, and "I" and "Taylor" were shadows and illusions of each other.
Jack surrendered to the police, and Taylor followed. In their fight, the gun in Taylor's hand ran into Jack's hands naturally and magically. Jack couldn't hit Tyler, so he pointed the gun at himself, but when the gun went off, Jack found that the person hit became Tyler, and he turned into a light smoke.
