This expansive drama follows Kariya (Kazuo Kitamura), an engineer from Tokyo, as he deals with the natives of a remote island. The inbred and highly eccentric Futori family is shunned by most of the other islanders, but Kariya must work with the strange clan in order to construct a well that will supply water to the sugar mill. As Kariya goes about his job, he encounters various Futoris, including the mystically inclined Uma (Yasuko Matsui) and her disgraced brother, Nekichi (Rentarô Mikuni).
