Kiwako sneaks into the home of Takehiro whom she had an affair with, and kidnaps his new born baby, Erina. Following this incident, Kiwako endlessly moves throughout Japan while raising Erina as if she was her own daughter for the next four years until she is finally arrested. When Erina returns home, the "normal" family life had disappeared. 20 years later, Erina is also having an affair with a married man and finds that she is pregnant with his baby. She decides to travel the footsteps of the past to find herself. (Shochiku)
