Momose moves to a quiet rural town after her husband's job transfer, only to discover its strict and sinister old rules. With her busy husband unable to attend the neighborhood association, she goes in his place. There she learns that its members have searched through her trash, criticized how she sorts condoms, and even complained about the sounds of the couple having sex. As her anxiety grows, the vice chairman declares that her enormous breasts themselves violate the rules and begins pawing at her nipples, revealing the threat behind the town's supposed order.
