Michiko is an ordinary housewife who, following her husband's retirement, moved into this house with her self-sufficient children. Her husband spends most of his days obsessed with fishing and walking, leaving him home only occasionally. And when he is around, he forces her into selfish sex without regard for her feelings. One day, the landlord comes by to check on a roof leak. Michiko happily enjoys a relaxed conversation with a man other than her husband for the first time in a long while. However, the atmosphere of the moment and a small accident end up stirring the landlord's desire, pushing him to cross the line.
