Reiko Natsuki, a 55-year-old milf who runs a dairy farm in Iwate Prefecture. Since her husband was diagnosed with dementia two years ago and moved to a care facility, she has lived a lonely and busy life all on her own. One day, she discovers an adult video her husband had been hiding, and her long-dormant desires begin to stir once again. Finding the production company's contact information on the back of the tape, she reaches out and comes into contact with "Nationwide MILF Search Party," a team scouting mature women in rural areas for adult video productions. Heading north along the Tohoku Expressway, a new journey begins.
