Life is not beautiful for Sachiko, a 13-year-old girl. She has no father. Her mother frequently fails to commit suicide. She feels uncomfortable in the school. Only one she can trust is Ogata, former teacher of elementary school who now lives far away as a nuclear plant woker. She often writes to him. She becomes drop-out, has some fun in streets with 'bad friends'. Although this brings back her smile, Natsuko, Sachiko's classmate, manages to bring her back to school. The new life in school seems to be better. But one day her mother's lover rapes her. Sachiko goes out to see Ogata.
