Since his wife died, piano tuner Ota has maintained a taciturn existence save for the rare cutting remark. Even before his wife's death, he avoided conversation--when she prophetically mentioned her impending death, he refused to look at the photo of the remote beach where she wanted her ashes scattered. One day an old puppeteer appears with an eerily realistic female mannequin named Aria. The ailing puppeteer asks Ota to find the piano on which his late wife used to accompany his performances. Despite the puppeteer's death, Ota continues the errand, if only to also find the beach that was so important to his wife. Just as he is about to set off, a mysterious young woman, who claims to be the puppeteer's daughter, joins him and the puppeteer's apprentice on the journey. Thus begins their wacky adventure through the picturesque seaside Hokkaido.
