Synopsis
Three maidens of poor background during the time of Song dynasty are sold by their families to the brothel Fragrance House run by madame Tall Kau (Lowell Chik). Susan (Karen Yeung) and Chinyun (Jane Chung) become closer during their training, while the third girl, ambitious Fanny (Tung Yi) keeps her distance. Eventually, the virginity of Susan is auctioned and bought by the horse tradesman Lui Tin (Elvis Tsui) from Lin'an but Lui gives Susan to Chu Chi-Ang (Timothy Zao), a young and inexperienced scholar he has befriended at the brothel and takes Fanny instead. Susan and Chi-Ang fall in love and Fanny, although she is taken as a concubine by Lui, knowing that Susan was Lui's first choice, grows increasingly jealous of her. After Chi-Ang runs out of his fortunes and is forced to leave the brothel, Lui buys Susan from Tall Kau and brings her home as a new concubine. Now, Fanny is convinced that Lui has an unmatched affection for Susan and plots for revenge.
