Fat is hiding in the house of Dik Wan who grows up with his daughter Ghik Fang and the two are very fond of each other. San chases after Fat but is beguiled by him and thinks that he is dead while Fat after murdering Wan's father lives in seclusion with Fong and Wan who is still in the dark about the murder. Dean makes great strides in his skills arousing the fear of Si who takes advantage of his love for Wan and makes Dean stay in prison willingly.
