Izumi was abandoned by his parents, so now he commits burglary, targeting women and the elderly. Chased by the cops, while on the run, he helps an injured elderly woman, Suma in the mountains of Miyazaki Prefecture. Izumi then stays at her home and, at first, keeps an eye for money that he can steal. The people in the village though think Izumi is Suma's grandson and take care of him, making him change.
