Anna Mishashi is a housewife struggling with her relationship with her husband after childbirth. Burdened by daily stress and physical changes, her sex life with him has gradually fallen apart. One day, she meets a group of male construction workers hired to renovate her home. Unconsciously aroused by their sweaty, muscular bodies and raw physicality, Anna begins to feel desires she hasn't acknowledged in years. Meanwhile, the company's boss, who has grown increasingly interested in her during his visits to discuss the project, takes advantage of a quiet evening when no other workers are around and makes his move. Initially resisting, Anna eventually gives in—her long-suppressed sexual frustration overwhelming her willpower. Surrendering to the man's powerful, aggressive sex, she is consumed by pleasure she's long been deprived of. Gradually, her heart and body drift entirely toward him, ensnared by the intoxicating thrill of forbidden desire.
