Gu Manzhen (Chien-Lien Wu) is an educated girl, working in a Shanghai factory as a clerical assistant. Her elder sister Manlu (Anita Mui), who works as a nightclub hostess, supports her family. At the factory Manzhen meets two male former classmates, Xu Shuhui (Huang Lei) and Shen Shijun (Leon Lai), and the three become firm friends. Manzhen falls in love with the introverted Shijun, who hails from a wealthy family in Nanjing and is working in Shanghai because he does not want to inherit his father’s merchandising business.
