To find out her mother's whereabouts, OI-KIU joins forces with MAK SEI to disguise themselves and follow TUNG. Surprisingly, they see CHING-MUI get entangled with TUNG, so they not only get suspicious of the relationship between CHING-MUI and TUNG, but also pretend to be gangsters to chase him off. However, OI-KIU cannot help getting suspicious of her own background. KA-KA goes to see CHOW CHING and apologize to her for having wrecked her relationship with her ex-boyfriend, but CHOW CHING refuses to forgive her. CHOW CHING eventually breaks up with KWOK-WAH. CHOW CHING asks KA-KA out to a fish raft, and while there, she accuses KA-KA of stealing her ex-boyfriend and murder. KA-KA uses what she learned from MAK SEI and the others to argue with CHOW CHING, the two end up fighting against each other. It's like déjà vu all over again. CHOW CHING falls into the sea and everything comes to light.
