In China in the early 1930s, sisters Junan and Yinan are inseparable. Junan enters into an arranged marriage and falls in love with Li Ang, her soldier husband. Separated from him when the Japanese invade China, Junan sends the unmarried Yinan to keep her husband's household. What is intended as an arrangement of convenience turns to betrayal when Li Ang and Yinan have an affair. As China is divided by communism, the family is also rent in two with part moving to the United States and the others remain in China - separeated by distance and betrayal.
