Momona moves to the countryside after her husband quits his civil-service job and begins working for a delivery company. She talks back to rough, old-fashioned veteran driver Oki, who retaliates by forcing himself on her. Too kind for her own good, Momona later apologizes for what she said and is gradually made obedient during their delivery route. The newlywed wife sinks deeper each time the married driver uses her inside the truck.
