Daikichi learns that his recently deceased grandfather has an illegitimate daughter with an unknown mother. The girl's name is Rin and she is just 6 years old. Everybody in Daikichi's family looks at the girl as an embarrassment and wants no part of her. Disgusted by his family's attitude, Daikichi decides to raise Rin by himself, even though he has no experience raising a child and is still single.

A case-hardened cop is pitted against a young eco-terrorist. The title "island" is an artificial construct in Tokyo Bay, a mountain of garbage, a by-product of Japan’s economic boom years. The film’s protagonist Alan works there, almost buried under society’s detritus; his growing obsession with the search for “what has been lost” turns him into a "dangerous" activist. He targets the industrialist Wada, whose chemical factory secretly discharges toxic waste into the environment. But the cop Terayama, who thought he’d seen it all, starts researching eco-activism and soon suspects the haunted, taciturn young man he’s encountered in the neighborhood.
