It soon becomes evident that the Chinese master's son is the most talented player that the Japanese master has ever encountered, and he convinces the boy's father to let him bring the child back to Japan to train him as a professional Go player. Years pass, and as the young Chinese master grows to maturity in Japan, the Japanese invasion of China forces him to choose between his triumphant career and his loyalty to his native country. His decision is complicated by his marriage to the daughter of the Japanese master, with whom he has produced a child. His choice will profoundly alter the lives of two families. Their saga serves as a reflection of the tragic relations between their two great countries, and the possibility of reconciliation and healing.
