Yuka returns to her husband's rural family home for the third anniversary of her father-in-law's death. She dislikes her crude, overly familiar brothers-in-law but cannot avoid them because they maintain the property. As soon as she arrives, a work emergency calls her husband back, leaving her alone for three days to help with the memorial. After the service, she spends a hot, sleepless night in the guest room—until the brothers come in and assault her.
