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.
'Human Comedy in Tokyo', describes ordinary everyday lives without any significant incidents. Various dialogues are elaborately woven to bring tiny splits in human relationships to light, and through the three episodes the characters have their moments of realizing that they are actually in solitude.
