In 1937, Manchuria was occupied by Japanese forces. Ku Ping On (Myolie Wu) and a brother-like friend Tin Hau Yi (Ron Ng) brought her sick mother to Nanjing to search for her father Ku Man Chai, owner of the biggest rice company in Nanjing. She discovered that Hau Yi, whom she considered to be her fiancé, was actually in love with Cheng Yuet Fung (Lelia Tong), the fourth wife of her father. Afterwards, Poon Sai Cheung (Sunny Chan), who helped the Japanese, "bought" Ping On (Myolie Wu).
