WA is a magazine journalist. His corpse is found in the woodland near Butterfly Stream. He was hit with hard objects and died for losing too much blood. There are many mysterious points about his death. His house had been searched by unknown persons after his death but his money was not taken away. Moreover it is found that over one million dollars has been deposited in his account. The police suspects that WA was killed as he wanted to disclose some scandals. As WA was dealing with LING, who is a singer, LI, FUNG and MIN, who are actresses, they become the targets of investigation. FUNG invites MIN and LI to act in a film invested by her. FUNG and MIN have announced their engagement. LI falls down from a ladder in the studio and dies.

It is realized that LI is not involved in WA's case. She needed money not because of being threatened by WA, instead she used the money to help her brother. As the screws had been loosened before she fell from the ladder, it is clear that she was murdered. YI thinks that it is only a joke instead of manipulated homicide. FUNG and. MIN have announced their engagement and the ceremony takes place in FUNG's house. However FUNG announces it is only a gag. He will not marry MIN. MIN feels being fooled. She is discontented as FUNG has another lover. She is on the brink of collapse but she still promises to act in the film. She tells the journalist that she wants to avenge her being humiliated. When they are acting, MIN shots FUNG with a real gun. FUNG dies and the others are shocked.

MIN is arrested. In MIN's car, YUNG finds the forgery gun. Most likely she has left it in her car and she wants to destroy it. At the same time, an informant reports that the gun was sold by a drugs smuggler to a girl looking like MIN. MIN is accused of committing homicide. The police starts questioning FUNG's previous lovers. They are surprised to know that all the “lovers” are gags of the film making company. All the “lovers” state that FUNG is a good man.

The case becomes more complex as the solicitor announces that FUNG wants to give one-sixth of his fortune to his manager SAU and one-half to his lover MIN. After consideration, the police figure out that LI died for MIN as MAN should be the one on the ladder. Thus the one being threatened may be FUNG. A camera is found in FUNG's house. The film is finished and the photographs are shocking. MIN goes to FUNG’s house where she sees SAU putting on dresses. In fact FUNG and SAU are lovers. Their abnormal love was found by WA who blackmailed them. SAU killed WA to keep the secret. Later FUNG fell in love with MIN. FUNG changed his mind where he knew that SAU had killed WA for him. However he did not want to continue the love. SAU hated MIN and wanted to set up a trap to frame MIN having killed FUNG. His plan was spoiled by the video tapes.
