The film begins with footage from ''Asahi Shimbun'''s special expedition to the ''Yamato'' wreckage in 1999. The narrative then shifts to the present on 6 April 2005, where a woman, Makiko Uchida, is visiting the Yamato Museum in Kure, Hiroshima. She is looking for a boat to take her to the site where the ''Yamato'' sank, to honor the crew on the 60th anniversary of the ship's last battle. Katsumi Kamio, a survivor who is now a fisherman, agrees to take her after he discovers she was an adopted daughter of Naval ranks of the Japanese Empire during World War II Mamoru Uchida, a fellow crewman and close friend who he thought went down with the ship.
