The husband goes to work day and night, leaving only the wife and younger brother at home to keep each other company. Sometimes when the husband doesn't come home, the wife goes to the younger brother's room to sleep because she is afraid of ghosts. Seeing the sister-in-law dressed provocatively before going to bed, the young man becomes aroused but has to restrain himself because she is his beloved brother's wife. However, both the sisters-in-law eventually realize that they both have sexual desires, and of course, having sex is inevitable.
