A group of prisoners were doing a variety of activities on the courtyard. Big Fool (William Ho) and Crazy Bill (Tommy Wong) were playing basketball where Bill kicks the ball towards Tung (Ben Wong), who kicks it away. Bill felt humiliated by it and stars a fight with Tung where Tung ends out hospitalized. During hospitalization, Tung thinks about the time when his family moved to another house and opened a food stall nearby. However, their stall was burnt by triad leader Sing (Bill Lung), who constantly bullies Tung's family and also raped Tung's girlfriend, Sau (Iris Wong). Unable to tolerate Sing's bullying, Tung kills Sing by chopping him to death, which leads Tung to being imprisoned.

Three young girls - Mon, Jo Jo, and Ida - with widely differing personalities, live together in the same house and come face to face with the faults of the men in their life. Mon, who works as a broker in the stock market, would like a change both professionally and romantically and has her eyes on married Michael; meanwhile he harbours fantasies of raping her. Ida works hard to pay off the mortgage with her boyfriend Andy; but he is too lazy to find a job after a year on the dole. The only man Yo Yo loves is Jack Daniels, spending every night in a bar getting drunk even though she is has a son and a daughter to take care of.
