Two enemies, a Japanese scientist's wife and a Chinese peasant woman, were drawn together in an unusual situation during the Sino-Japanese war (1937-1945). Their daughters grew up together and became inseparable. When the war ended, all Japanese were repatriated back to Japan. Not wanting to subject an innocent child to the unknown harsh life of a post-war Japan, the young scientist couple left their daughter in China to be cared for by the Chinese peasant. As soon as the relationship between China and the United States returned to normal, this Japanese couple returned to China to look for their long-lost daughter. This is a story about conflicting emotions: friendship and animosity, love and hatred, kindness and cruelty, trust and betrayal.
