A young woman named Kiko moves to a small town by the sea. She lives in a house that has been empty for a long time, doesn’t work anywhere, has a scar on her belly, and the locals start gossiping whether she escaped from the Yakuza in Tokyo. Kiko is grieving the loss of a friend and, at night, turns on in her headphones the voice of a fifty-two-hundred-year-old whale—the loneliest creature in the world. She couldn’t hear what the most important person in her life was trying to tell her, so now she hopes not to miss the songs of other lonely whales, because she is one of them too.
