The film follows the lives of the Haruno family, who live in rural Tochigi Prefecture, the countryside north of Tokyo. Nobuo is a hypnotherapist. He teaches Go to his son Hajime. Hajime becomes an excellent Go player, but he has a rough time with girls and puberty. Yoshiko refuses to be an average housewife and works on animated film projects at home. She uses assistance from grandfather Akira, an eccentric old man who is a former animator and occasional model.
Eight-year-old Sachiko periodically sees a silent, giant-size double of herself which mimics or benignly watches her. She contemplates ways to rid herself of it. Uncle Ayano is a sound engineer and record producer who comes to stay for a visit. He engages in inward reflection, seeks closure regarding an old relationship, and recounts a childhood experience—a tale that influences Sachiko and ties into later events.
