Kanae's husband disappeared without a trace while on a union trip. Though usually headstrong and independent, the woman becomes plagued with worry over what happened to him, and is unable to move on with her life. Thus, Kanae decides to hire a private investigator, and keeps running the public bathhouse to the best of her abilities. As he tries to figure out the truth about her husband, Kanae must deal with the stress from a work-intensive job, meddlesome neighbors, and recurring nightmares in which she is drowning.
