This is the story of the incredible life of Dr. Aidan MacCarthy (1913-95) the only person to have survived the two events that mark the beginning and end of the Second World War. He was evacuated from the beaches of Dunkirk after three days of relentless attacks in May 1940, and he was trembling in a makeshift bomb shelter in the center of Nagasaki when the atomic bomb destroyed the city in August 1945.
