Arina Hashimoto stars in her first train-molestation feature. It begins when she boards the wrong carriage: a strange pressure against her ass, then hands moving over her clothes and slipping inside her underwear. Too terrified to cry out, she is overpowered and raped. Footage of the assault is posted on a molesters' website, marking her as a target. With no time to escape, she is attacked by one man after another and steadily driven toward psychological collapse.
