57-year-old Chiyoko Shimizu is the elegant boutique owner operating a shop in a local shopping district. Running a small, traditional store, she continues the business more as a hobby thanks to her husband's stable income. On slow days, she often thinks about trying something new. She recalls how, during chats with a regular customer's friend, they'd joke, "Well, since we were born as women, we should probably try doing a porn at least once." Then one day, she received an actual offer to appear in a film—something she never imagined would happen to her. This unexpected turn of events, intersecting with a long-held fantasy, becomes the compelling heart of the production.
