Underworld swordsman Ah Nian (Chen Xiaochun) is finally released after eight years in prison. Ah Nian, who is tired of gang life, hopes to smoothly take care of the two sisters of the United States and the United States to be admitted to college. A Nian and his good friend Jiuhui, who has been playing since childhood, work together to manage the decoration company and are determined to quit the world completely. However, the two sisters made Ah Nai quite worried. Damei made a good-tempered mixed-race boyfriend, while Xiaomei was tainted with bad habits in the environment of rampant violence on campus. On the other hand, during his many years in prison, the rising star of the gang, Joni, did all the bad things of usury and vigorously expanded his sphere of influence, causing dissatisfaction with the elder uncle Bao (played by Wang Tianlin). Uncle Bao invited Ah Nian to come out of the mountain to restrict the power of Joni. Although Ah Nai refused, Johnny frequently attacked Ah Nian in order to avoid future trouble. Jiuhui was beaten by Johnny's gang, and Ah Nian's two sisters were also taken by him. The unbearable Ah Nian decided to fight back.
