CHIU's corpse is found along a river. On seeing the decaying corpse, LUNG feels sick. KWAN misinterprets HUNG's intention, thinking that he invites her to see an opera together. In fact she is only a baby-sitter. LUNG tells CHIT her life-saver when she was a child. In fact her life-saver is YI but both do not know. YUNG and CHIT come across TUNG when they are dating. TUNG wants to kill herself but is saved by them. CHIT introduces FAY to be a part-time photographer. FAY is excited. TUNG is YUNG's old friend. She tells CHIT her unpleasant experience. She married a musician LIM. LIM was unemployed, thus she worked hard to earn their livings. She was shocked and wanted to commit suicide as she found the filthy relationship between LIM and her sister LAM. Later LAM is found dead.

LAM is dead and her corpse is terrible. Her neighbor SA reports that before LAM died, there was loud music. YI is careless and breaks SA's Mickey mouse glass. YUNG and YI check the four involved persons. They know that one of them was sent to hospital in Macau. They suspect CHIU as the killer. An old lady comes and recognizes that the corpse is CHIU. YUNG feels strange as TUNG cannot identify the corpse correctly. In the television program, TUNG advises LIM to return. In fact she uses the name of the song to warn LIM not to show up. YUNG cannot realize her trick immediately. TUNG refuses to eat KWAN's cake as she is allergic to eggs. LUNG also gets the medical report from the hospital. YUNG accuses TUNG of telling lies.

YUNG discloses TUNG's trick of misidentifying the corpse. TUNG tells the truth. In fact TUNG and CHIU went to Macau first. Then they asked LIM and LAM to discuss the matter. However they could not compromise. YI takes care of LUNG and tells her that he saved a girl when he was young. LUNG realizes that YI is her life-saver but she does not have the courage to tell him. YUNG follows TUNG and finally finds LIM. YUNG arrests LIM. LIM tells YUNG the whole story. CHID loved LAM and even stole his company's money for her. However LAM loved LIM. Therefore CHID planned to kill LIM after killing LAM. However CHIU was killed by LIM by mistake. After telling YUNG everything, LIM rushes into towards a car and is knocked down. He dies in the street.
