The fifth film in the Toho Diamond series, following "The Hateful Thing." Based on the true story of "Zoo Story" by author Fukuda Saburo. During the Tokyo air raids of World War II, Zen-san, an elephant keeper at Ueno Zoo, is faced with the heartbreaking task of euthanizing Tonki, a beloved elephant, due to food shortages and wartime pressures.
