Sometimes, family treasures hold the key to family secrets… While packing up the family home, Danny's daughter, Jules, finds a black box hidden at the back of his wardrobe. Danny suffers from post-traumatic stress syndrome and has been in and out of psychiatric hospitals for years. The unexpected contents of his box take Jules and her sister on a journey to find out what really happened to their father in occupied Japan after the war. What they discover is a love story about ordinary people-a man and a woman, a child and a father-who lived extraordinary lives. This is a tale of mateship, bravery and a romance that blossomed against all odds.
