The hidden shame and sense of guilt within a married woman are stirred deeply. A man who organizes a swinging enthusiasts' circle approaches her, fulfilling her husband's cuckolding fantasy. The woman is Mika, 28, married for three years, no children. She initially claims she came only to hear the proposal seriously, having been asked by her husband, but gradually her defenses weaken. Convinced, she undresses and allows herself to be taken by a man she's never met before. Facing the camera, she is made to narrate her own depravity in real time. As the acts grow increasingly intense, so does the married woman's arousal. Her appearance captures the inner conflict between a pure heart drawn to love and a mind awakening to desire.
