Recap of episodes 1-11 of Tetsujin 28-gou, originally broadcasted between episodes 11 and 12 as a New Year special.

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.
