The film is adapted from the famous Japanese manga "Cockfight". The young boy Cheng Jiuliang saw his parents die tragically in front of him, but was regarded as the murderer of his biological parents. From then on, his life began to suffer. He was brutally abused in prison and was ostracized after serving his sentence. He went from a promising boy to a marginalized person in society. He was raped, became a male prostitute, and took drugs. He was forced to the bottom of darkness and was helpless and angry and went on a bloodthirsty road. Shawn Yue shaved his eyebrows and dyed his hair white for the film, completely changing his appearance, which was a major breakthrough since his film career.
