The film follows a schoolgirl (played by Minori Majokoro) navigating Tokyo’s crowded private railway lines, where she encounters a molester (chikan). The narrative unfolds through loosely connected vignettes, blending public risk with private intimacy. Unlike the first film’s marital subplot, this sequel centers on the protagonist’s journey from victim to “Supervixen,” embracing or manipulating the encounters in train cars, stations, and secluded settings. Key scenes include initial groping, seductive teasing, and a climactic role reversal, all wrapped in schoolgirl uniforms and POV shots for immersion.

Natsumi (Ai Takeuchi) is forced to work in a steel factory in order to pay off a debt, a factory notorious for employing women with "dark pasts" as slave labor. Tsukada, Chief of Security places Natsumi in a team of four women led by Atsuko(Nagisa Umeno). When one worker fails to follow instructions, Tsukada rapes her, and Natsumi is next on his list. Natsumi tries to fight the insanity, but is hindered by managing director Hideko and factory president Kamiyama. It is up to Natsumi to take on the evildoings of the factory.
