In 1945, a group of young women from a school in Hiroshima were taken away for work during World War II. The rest of the first-year students remained behind and had to adapt to life as teenagers in an almost empty town due to wartime conditions. On August 7th, their lives changed forever when an American bomber dropped an atomic bomb on Hiroshima. This event is commemorated annually on its 43rd anniversary with a tribute to the victims of the atom bomb.
Based on the diaries left by the students of Dai-ichi Hiroshima Prefectural Girls High School, the program illustrates their fleeting youthful days and how they had felt joy in becoming high school students even in a time of war with animated scenes, while documenting the profound sorrow of the bereaved families.
