Shijie (Jay Chou) was expelled from the Kung Fu School for getting into trouble. He is an abandoned child who has never left the school to venture out. Although the school has an unlearned principal and a weird fourth uncle, it is still a shelter for Shijie. On the first night of wandering outside, he was spotted by Uncle Li (Eric Tsang) because of his ability to throw soda cans into the trash can. Uncle Li lived a poor life, but he had many tricks. He helped Shijie design a plan to "play basketball to find relatives". He used Zhijie's expertise to make money and become famous. However, the basketball team needs the permission of the captain Ding Wei (Chen Bolin) to enter. Ding Wei's sister Lili is the girl that Zhijie has a crush on, but Lili has a crush on center Xiao Lan. Shijie's talent made it easy for him to enter the basketball team and also made the team easily enter the championship game of the college basketball game. When he was about to confront his old rival Li Tian, his former comrade-in-arms and now his opponent, Shijie realized that Ding Wei's decadence was not only because Li Tian had taken away his girlfriend, but also because he had lost himself on the basketball court. This is not only a basketball battle, but also a psychological battle.
