Based on an originally banned book by the surgeon Takashi Nagai, who died of radiation sickness in 1951 after witnessing the bomb blast in Nagasaki, this film is told from the perspective of his son; of memories recalled while on a plane coming home from a conference. He remembers how his father was himself fighting leukemia and the effects of radiation as he treated radiation victims. His mother also died, leaving both her children in the care of their grandmother. Nagai's son becomes a journalist, and when filing reports from battlefields around the globe, expresses his relief that no atomic weapons were ever used again.
