Unable to endure a marriage in which she and her husband have forgotten how much they mean to each other, Satomi sets off alone on a journey of self-discovery. She wanders without a destination, holding out her hand to passing cars in hopes of catching a ride. Almost no one stops, and when a man who finally picks her up attacks her, she learns how harsh the world can be. Yet as the journey continues, she meets kindhearted people, bares her flawless body, and opens up to them both emotionally and physically—as if trying to reaffirm her own existence.
