Sex & Zen III continues along the path of sexual enlightenment revealing more of the seductive secrets from one of the most forbidden books in Chinese literature. This stylish Wong Jing production delivers explicitly erotic and often bizarre imagery and features a host of Hong Kong's most nubile Cat III babes. The story follows the live of three young girls sold into China's most notorious brothel 'The Fragrance House' where sister Kau teaches Susan, Chinyum and Fanny the oriental way of pleasuring men with her legendary sucking skills until she sells her virginity to the highest bidder. When the competition is held for the deflowering amongst the highest bidders is Sir Lui, a wealthy trader and Chu, a young inexperienced scholar who strike up a friendship. That evening Susan is the prize - and Lui bids for her as a gift for Chu and takes Fanny for himself. The next day Lui takes Fanny as his concubine even though he really loves Susan. When Chu is forced to leave 'Fragrance House', Susan refuses to have sex with the customers and is cruelly tortured until the sexually perverted Lui arrives and forces her to become another one of his concubines. When Fanny murders him and frames Susan the plot thickens. Only her Chinyum and her lover Chu can save her from a fate worse than death.
