Cashing in on the boom of period sex films following the surprise success of Sex and Zen, Ivan Lai spins this bizarre erotic drama. Following the death of her father, beautiful maiden Siu-ching (Ching Suet-ngan) reluctantly sells herself into prostitution to pay off her family's debts. When the virginally lass initially balks at her professional duties, Miss Ng (Yvonne Yung Hung) -- the brothel's ruthless madam -- threatens to dunk her in a boiling pot of eels. Siu-chang quickly changes her mind, and with the help of kindly worker Yat (Dick Lau), she soon becomes familiar with the ways of the prostitute. Meanwhile, a rival whorehouse hires a white prostitution from overseas, sending Miss Ng into a tizzy; buxom Sister Bamboo (Yuen King-tan) finds herself without clients when she accidentally smothers one with her oversized breasts; and the workers in the hose band together to nab a serial rapist whose victim of choice are prostitutes.
