Ah Xiao (played by Jiang Tao), Ah Tak (played by Lu Jue'an) and Zhang Liang (played by Qiu Shizhen) used to be regulars at the street basketball court, but for their own reasons, they temporarily put aside their beloved basketball activities. Until one day, the B team, the leading university basketball team in Hong Kong, came to the community to clean up the court. The neighbors, led by Dai Bo (played by Zhang Jicong), were unwilling to let the basketball court be occupied, so they challenged them. The three of them responded to Dai Bo's invitation and joined the neighbors to stage a confrontation game. In the end, the three of them combined their strength and Dai Bo's tactics to repel the basketball team and successfully save the court. The victory process was even posted online and became the talk of the town overnight. The captain of the university basketball team A, Feng (played by Chan Cheuk-yin), learned that his team was badly defeated by the neighborhood, and he was unwilling to take the regular players to the court to avenge the previous shame. Facing the attack of the orthodox basketball team, Sanzi and Daibo were defeated. In order to save face, the two sides made a vow to fight again in 6 weeks. As the coach, Daibo took Sanzi for special training and found Guangzai (played by Guo Jiajun) and Zhu Run (played by Liang Yip) to join the team. Under the leadership of Daibo, the five-member team challenged the streets of various districts in Hong Kong and gradually became an organized regular basketball team.
