Goda (Renji Ishibashi) is the introverted owner of a boarding house, where he routinely spies on his tenants through strategically placed holes in the ceiling. One afternoon, he witnesses the wealthy Lady Minako (Junko Miyashita), having a sexual encounter with one of the tenants, whose fetish is to dress up as a clown. Fully aware that she is being watched, Lady Minako kills her lover. Goda, does not go to the police. Instead he takes the opportunity to kill another lodger himself. Soon the two meet and a deadly trust is born.
