Gyun, an unknown person who came to Shanghai to work, agreed to represent the declining Chuanwu Boxing Gym to participate in the "Shanghai Fight Night" martial arts competition in order to earn money to treat his father's illness. To do so, he must overcome all the experts, prejudices, and himself.

By a fortunate coincidence, Gyun is inspired and encouraged by a girl with the same name. Therefore, he decides to form a lion dance troupe with his friends, Kat and Doggie, to break the constraints of reality and fight for themselves for once.
