In Pak Siu Yau's eyes, her three daughters – Sylvia, Constance, and Jessica – are as perfect as diamonds. She believes that the greatest blessing for a woman is to marry a wealthy man. To guarantee a better life for her daughters, she has started training the girls since they were young, hoping that they will marry into the richest families when they mature. Yau's persistence pays off, and her daughters all find a wealthy husband, but money does not really bring them happiness and the sisters are gradually lose themselves in vanity.
