Ten years before the outbreak of the Second World War in Asia, a Japanese Go master and his Chinese rival meet in China to play a game of Go (loosely described as an Asian version of chess). 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.

Their saga serves as a reflection of the tragic relations between their two great countries, and the possibility of reconciliation and healing..
