A few months after Mahiro and her husband move into the neighborhood, they are already fed up with the arrogant association chairman Ozawa and his cronies. At a meeting, the group hands them a camping notice marked mandatory. Her husband cites work and Mahiro says she cannot handle alcohol, but they refuse to accept either excuse. Told the women's group will attend, Mahiro reluctantly goes alone—only to find herself with three middle-aged men at a remote campsite with poor reception. Over the next three anxious days, her husband ends up witnessing humiliating footage of his wife.
