40-year-old married woman Kazumi (pseudonym) exposes her naked body to men other than her husband—what is her reason? A two-day, one-night documentary delving deep into the inner psyche of a married woman. Kazumi has no children and works part-time preparing ready-made meals. Her hobby is watching movies; in her youth, she dated an actor who appeared in one of her favorite films and married at 22. However, the relationship ended in divorce due to his infidelity. Several years later, she remarried at 31 to a man 12 years older, a divorced father she met at work. Thanks to her kind and considerate husband, the wounds from her first marriage healed, but as they grew older, their sex life faded, leading to a sexless relationship with no children. Carrying loneliness into her 40s, Kazumi reaches a turning point. "I wanted to confirm if I still have value as a woman..." Torn between guilt, love for her husband, and her own desires, an intensely chaotic two-day, one-night record unfolds.
