This is a story about a piano, pitifully abandoned in the woods, and a young boy, Kai, who grew up playing it as his favorite toy. Tensions rise as the International Chopin Piano Competition reaches the final day of its second round, and the local Polish favorite, Szymanowski, delivers a magnificent performance. But the best is yet to come when Kai Ichinose finally takes the stage and plays a Mazurka so profound it changes the very atmosphere of the hall.
