Father To Son

Van Baode's father left home for Japan fifty years ago to seek better opportunities and has not contacted the family since. His father's absence has been the greatest source of pain in Van Baode's life. For most of his life, Van Baode has stayed in the small town running a hardware store and occasionally coming up with invention ideas to apply for patents. However, a recent illness made him realize that his days might be numbered, prompting him to take his son, Van Daqi, to Japan to search for his father. What changes will this journey bring to their lives?
