He could no longer practice medicine. Kit (Wong Shu Kei) was in pursuit of Fai’s girlfriend Fung (Fennie Yuen). He set Fai up and got him into serious trouble. Fai was wanted by the police. In rescuing Fai, his friend Tai (Cheng Ho Nam) accidentally killed someone and he had to hide together with Fai. Then, Fai met Mui (Gigi Lai), daughter of his teacher Cheung (Wong Kam Sun). Mui was sweet and kind-hearted. Fai and Tam stayed with Mui during their flight. Fai took great care of Mui since she was having heart disease and would die suddenly. They became close, while Fai and Fung distanted. Then Fung was seriously injured in an attempt to save Fai. Fai couldn’t leave Fung, but he also wanted Mui. What could he do?
