Au Yeung Chun, a quiet pro boxer, aims to win the Asian Championship after his gym's lead boxer retires. Rival gym owners hold a competition backed by a corporation seeking profits through exciting matches.

Au Yeung Chun is a popular professional boxer and a record holder. He is quiet, stubborn, diligent and does not give up easily. Boxing gym King Boxing became his second home when his brother fled from his creditors a few years ago. There, he met boxing trainer Lee Shing Tung and laundromat worker Keung Sau Yin. With lead boxer Yuen Tin Zau's sudden retirement, Chun is determined to win the Asian Championship. Tomorrow Corporation, who has come to Hong Kong to develop the sport of boxing, gets rivaling boxing gym owners Lo Kin and Kam Shing Leung to hold a competition together. Lo of King Boxing trains his boxers with traditional methods. Kam of ACE, a retired boxer, trains with scientific methods. He also raises his boxers' value using commercial means. Tomorrow Corporation's Fan Siu Fung is glad that they are both keen on the collaboration as it will bring about what she is after - exciting matches and high profits.
