The workplace is part of an adult ex-offender rehabilitation role-play program filled with vicious young men. Though terrified, she keeps working for her husband's sake. Their leader, Haneda, targets her, overpowers her resistance, and rapes her. From then on, the men take turns gang-raping the J-cup married woman inside a truck with nowhere to escape.
