Summary

When his "mentor in crime" disappears, blond-coiffed Kakihara (Tadanobu Asano) vows to find out who's responsible. But he's also on the lookout for Ichi (Nao Omori), a sadistic killer who may be able to inflict the level of pain Kakihara so badly craves. Japanese filmmaker Takashi Miike takes inspiration from Hideo Yamamoto's manga, Koroshiya 1, to tell this bloody and bleak tale about the inner workings of the Japanese yakuza.
