Shodoshima, Kagawa Prefecture, is an olive island floating in the Seto Inland Sea. A piano was placed by a roadside station for a limited period. A father and daughter traveling together. Sisters playing duet of a memorable song played at a wedding. Childhood friends soon going their separate ways. A film director dedicating a song for her late husband. A singer-songwriter visiting her friend... Each from all walks of life come to play their melodies to share.
