The lives of three people intersect on a late bus ride that’s hijacked by a suicidal political flunky. Shingo is a miserable young desk cop bucking for homicide division. Tetsu is a restroom cleaning attendant who has a mentally ill father and a penchant for mischief. And Saki is a petulant druggist/chemist who was born without an eye and keeps her disfigurement hidden behind shades. Months after the hijacking, the trio lives re-intertwine as they playfully seek revenge for their unhappy lives, until the games become deadly serious.
