An adolescent's distrust of the world of grown-ups is often confirmed by what goes on around him in this offbeat drama. Minoru Masaki (Kengo Kora) is a straight-laced boy in his early teens who makes pocket money after school by delivering newspapers. Having been abused as a young child, Minoru takes a dim view of the world around him, believing drugs and sex have corrupted the culture of adults, and he has few friends his own age. One day, Minoru strikes up an acquaintance with Masato, a boy several years his junior. After playing catch in the park, Minoru goes back to Masato's house, where he's introduced to Satoko (Ogawa Miwon), Masato's mother. Minoru thinks he recognizes Satoko, and after spending a few days following her, he learns that she spends her afternoons working as a prostitute for Tawara (Tomorowo Taguchi), a pimp associated with the Japanese mafia. While Satoko's husband Hideyuki (Nao Omori) is unaware of his wife's secret life, he enjoys fantasies of her taking lovers, which are a far cry from the grim reality of her career with Tawara. M was directed by Ryuichi Hiroki, who got his start making soft-core "pink films" dealing with many of the same themes covered here.
