The film's protagonist, Michiru Toriyama, is a housewife who has been married for three years. Michiru and Ao met at work, and their marriage life gradually deviates from the ideal they originally envisioned. One day, Michiru learns about a subscription service called Buffet that provides safe extramarital affairs. Through this service, she can order everything from makeup and haircuts to dress rentals and date location reservations, while keeping it confidential. Michiru decides to join, and through her contacts with photographer Toshiya and the hospital police chief Kentaro, she finds herself trapped in a cycle of desire for self-recognition and out-of-control bills.
