A married woman, married for three years, lives with her husband's father. Her busy husband is frequently away on business trips, disrupting their sex life. One day, her sexually frustrated wife masturbates, only to be discovered by her father-in-law, who then gives her a sinister smile. Another day, her lover, a deliveryman, visits and they have sex, but again, their father-in-law witnesses it. He then uses witnessing her masturbation and infidelity as leverage to blackmail her into sexual intercourse. Under the threat of telling her husband, she has no choice but to submit to his demands. Furthermore, she is repeatedly assaulted at night, forced to orgasm by her father-in-law, whom she utterly despises.
