Nagasaki, 1945. Three nursing students, Tanaka Sumi, Ohno Atsuko, and Iwanaga Misao, return home when school is closed due to air raids, and spend some peaceful time with family and friends. However, at 11:02 AM on August 9th, the atomic bomb is dropped, and their daily lives are instantly shattered. The city is reduced to ruins, and despite their inexperience, the nursing students rush to provide medical care to the injured. Faced with the cruel reality that more lives must be buried than can be saved, the women continue to question the value and meaning of life.
