The Pure and the Evil

Alan Wong is a Hong Kong youth who is bent to climb up the social ladder. With the help of a foreign businessman's mistress and mixed ethnicity woman Erica, he joins a real estate company and he knows how to grasp on to opportunities and gets into high position. Later he meets Cheung Ting Ting, a Mainland Chinese girl who illegally came to Hong Kong and sees her pities her and also falls in love in her.

Dr. Poon is a psychiatrist who espouses the therapeutic benefits of wild, screaming group sex. He tells Susan, a recent divorcée who is disenchanted with love and men, that the only way she is going to get over her ex-husband is to watch him have sex with some other woman. When she acquiesces to her shrink's suggestion, Poon insists that he also be present for professional reasons. Meanwhile he coerces his Mainland-born nurse Siu-ying to attend these swingers' parties posing as his wife. There Siu-yang meets Lee Keung, a love-starved divorcee, who falls for the comely young nurse. Soon the two long to flee the soulless, bacchanalian group with which they have become intertwined.
