Director Kyosuke Murayama organized a private filming trip, inviting an acquaintance—a married woman—to join. Participating casually as a day trip, Hitomi (pseudonym), 30 years old, married for five years with no children, joins the excursion. Her husband frequently works night shifts, and she spends her days working part-time, leading to dwindling conversation and no sexual intimacy for several months. Sharing a mutual love for sake, she had previously met Murayama, a regular customer at a Japanese restaurant. Drawn by the promise of fine sake, she agrees to join the day trip. Soaking in hot springs and drinking alcohol, she gradually lets her guard down, surrendering her body to intoxication. Her genitals are licked, she reaches climax, and continues craving more pleasure. The film captures her intensely engaging in sex with a man she knows, hiding it from her husband, vividly portraying her drowning in pleasure. As she escapes her daily routine, the raw fulfillment of a married woman’s suppressed desires unfolds in a deeply moving way.
