Sometimes life comes at you quickly. Chisako (Anne Watanabe), an author and grieving parent, has returned to her rural hometown after a long absence to deal with the affairs of her father, Kozo (Eiji Okuda), as he slips into a fog of dementia.
While driving at night with her old friend Hisae (Aimi Satsukawa), after having a few drinks in the city, they hit a boy on the road and knocked him unconscious. Hisae, who was driving, begins to panic about losing her job, so they agree to take the child back to Chisako’s house instead of calling the police.
As they remove his clothes, they discover that his body shows signs of physical abuse. However, when he wakes up the next morning, he claims to have no memory of his past life, or even his own name. After paying an incognito visit to the boy’s real family and confirming her suspicions, Chisako – who lost her own son in tragic circumstances several years earlier – makes an impulsive decision to adopt him.
