With the support of the head of the Police Authority, Guangzhou’s top villain Ho Kei-Kin (Dayo Wong) has been riding roughshod over everyone around him. He is so manipulative that he has explored every possible means in his fight for a house with the buck-toothed owner Ling Yuk Tsui (Cecilia Yip).
However, he was originally a kind-hearted person. His change of heart was due to him being mistreated by his father back when he was a child. His father once nailed him inside the coffin, which led to his fear of being trapped in the dark. When he grew up, his father left the town with one of his many mistresses and her son. When Kin went to confront his father, the father retorts and says that Kin wasn't really his biological son, saying that some stranger is his father. His father also said that he was glad to have a son who is more skilled than him and that Kin is nothing but a weakling to him. After that, he left by boat. Angry by this, Kin cursed at his father, his mistress and their son, saying that they won't live to regret this. When he tried to redeem himself by fighting the town's crime lord, he was defeated by not only the crime lord but also the townspeople. Fed up with the town, he causes chaos to the town by wrecking and burning some stalls. As the crime lord and the townspeople were about to subdue him, one of his henchman told him that the boat that carried Kin's father exploded and that everyone on that boat died, including his father, his mistress and his son. Kin said that he was happy that happened because they had insulted him and that his prophecy of them not living to regret it had come true. He also declares that he won't go by his given name. He will only go by the nickname Gan Yan-Kin (Bully Kin). He decided that to get through life, he must treat others really badly as they have treated him.
Tsui is happy to have met the upright and honorable Wong Fei-Hung (Dominic Lam). Interested in stirring up trouble, Kin tries to recruit more students fo
民國初年，廣州「旗下街」惡人「奸人堅」何其堅(黃子華飾)，靠得警察廳廳長方天圓(陳榮峻飾)撐腰，終日橫行霸道，傳聞有指奸人堅其父對不住他而弒父，連惡人趙猛丁(王俊棠飾)也要忌他三分，之後警察廳廳長因為風水問題，希望能收回姑婆屋，奸人堅答應幫忙，但姑婆屋的屋契一直由凌玉翠(花名「哨牙鬼」)(葉童飾)保管，為了接近「哨牙鬼」，奸人堅使出美男計奪取姑婆屋，從而令他能順利成為「旗下街」唯一話事人。
此時武術奇才黃飛鴻(林嘉華飾)守孝三年後來到旗下街，他一生好儆惡懲奸，不斷幫助有需要的人，其後更在旗下街成立「寶芝林」和招收徒弟，欲將祖傳武術和做人精神發揚光大。黃飛鴻的出現令到奸人堅十分麻煩，其後奸人堅更因黃飛鴻破壞了他的大事而失勢，之後他痛改前非，拜黃飛鴻為師，黃飛鴻接受，因為他一心希望能感化奸人堅，使他重回正途，但另一方面奸人堅卻想暗中破壞「寶芝林」和飛鴻的名聲。
