A group of children in Sau Mau Ping killed a teenager. They moved the body and destroyed the body... The bad youth king was brave and fierce. He and his right-hand partner Abi clashed with another group of bad elements, Hei Zai and others, to protect his younger brother Aji. Hei Zai was defeated and had to retreat. On the other hand, Fan Shu, who was born in Thailand, worked at a garbage station, but the idle Fan Shu pushed the work to the honest and dull Third Uncle (played by Li Jianren), and used violence against the latter from time to time. Fan Shu won praise for the children in Thailand and took the opportunity to recruit younger brothers to establish his own power. Hei Zai found Fan Shu and asked him to cooperate with the king, but the two were recruited by the king who was good at fighting. Since then, the "Dynasty" party under the control of the king has been formally established. A group of young people were idle all day and bullied the third uncle. Aji, who had a good relationship with the third uncle, was dissatisfied, but it brought about the disaster of killing... This film is adapted from real events.
