A young wife, 'Mei,' who is dissatisfied with her husband's private life (womanizing) one day feels attracted to a subordinate of her husband whom he invited home. Mei exchanges contact information with her husband's subordinate. During the three days when her husband is away on business and doesn't return home, they meet secretly every day at home, passionately pursuing each other and having sex non-stop. Entrance hall, bathroom, living room—everywhere is a place for pleasure over 72 hours. 'Better than my husband...' The secret relationship that would be over if found out excites the two of them.
