Occasionally, the scenery and scent of that day rise to the surface, only to waver and disappear like bubbles. Narasaki, a psychiatrist at a small hospital, is researching why people forget things. Why do people forget? Is there no way to not forget something precious? As she delves into the mind of a patient, she finally reaches that deep, deep bottom. Sachiko, a designer with an office in the city, works as if possessed by something. Despite her colleagues' concerns, she continues on, developing a mental illness and seeing visions of her ex-lover. As she chases the traces of her lover, she discovers a dark, long tunnel. Takako, who lives in a nursing home, cannot remember how she broke up with her same-sex partner, who has been with her since kindergarten. Then she meets a woman who resembles her partner and gradually begins to regain her memories. As she opens the door to her memories, she finally enters a cold, quiet room. Where will the three people, each searching for their past with their own objectives, end up? The three stories quietly progress through their mundane lives, ultimately returning to the same place.
