Kaneko, imprisoned for violence, was a man who would get angry even at his wife if she came to visit. It was the power of family - his wife, child, and uncle - that led this good-for-nothing to start a new life. Kaneko now runs a commissary that provides items to people imprisoned like he once was and visits them on behalf of their families. However, the peace is shattered when a young girl, his son’s friend, is found dead.
