Two police detectives and SV2 investigate a series of mysterious acts of deadly destruction occuring in and around Tokyo Bay.

Izumi (Kento Hayashi) was abandoned by his parents. He now commits burglary, targeting women and the elderly. He is chased by the cops. While on the run, in the mountains of Miyazaki Prefecture, he helps an injured elderly woman, Suma (Etsuko Ichihara). Izumi then stays at Suma's home. At first, Izumi keeps an eye for money that he can steal. The people though in the village think Izumi is Suma's grandson and take care of him. A change takes place in Izumi.
