Au-Yeung Wai-Lan (Yuen Qiu), owner of a martial arts training school, is reunited with her long-lost son Goo Yu-Cheung (Kevin Cheng) after years of agonizing separation. On his return home, Cheung is shocked to find that his younger brother Goo Yu-Tong (Kenneth Ma) has been critically ill and that his father was murdered long ago by Wing Dak (Lam Ka Wah), the existing director of a pharmaceutical company and a bitter old foe of the Goo family. Cheung has never been into kung-fu but shows glimpses of his potential when he strikes back at the impudent, arrogant Wing Man-Gwan (Jacky Heung), also the son of Wing Dak. Pinning all her hopes on Cheung, Wai-Lan not only teaches him a special set of kung-fu skills created by the family, but also registers for him for the Guangdong Boxing Championship Tournament. Out of the blue, Cheung' s opponent in the final turns out to be Man-Gwan.
Cheung starts losing his bearings after achieving growing success and recognition in the field of martial arts. Caught up in the love triangle between was his adopted sister Ying Ngan-Ming (Natalie Tong), his dream girl Chow Bing-Bing (Nancy Wu) and himself, Cheung is utterly confused and exhausted, which later causes his failure in the final tournament.
