Wife Shizue (pseudonym) embarks on a hot springs trip hoping to resolve the lack of intimacy in her marriage. Married for eleven years with no children, she works in child welfare, following the path of her uncle who inspired her career. Recently transferred to a new care facility established by her uncle, her husband—older and from the same workplace—has been stationed at another facility since their marriage. His constant busyness caused their relationship to grow cold, and fearing life would pass her by unchanged, she decides to take this journey. After an incident where a boy from the facility asks her to teach him how to kiss, she begins awakening to her own femininity. Torn between anxiety and anticipation, she starts her trip, gradually becoming highly sensitive to sexual stimulation, her body growing increasingly aroused. Drawn completely into these new sensations, she experiences climax after climax. A married woman's suppressed desires ignite, and this solitary night at the hot springs becomes a new beginning for her.
