This documentary was filmed in Ishinomaki, a city with a population of about 170,000 in Miyagi Prefecture, located on the Pacific coast in northeast Japan. The mega earthquake and tsunami on 11 March, 2011 devastated the city leaving 3,943 people dead or missing. Among them, 182 were elementary school children. With an earthquake and tsunami that no one had experienced, at that time, how did those at the school judge, handle, and act on the situation? What did the teachers do? How did the children react? What did the parents and family members of the children do? 37 people affiliated with Kadonowaki Elementary School in Ishinomaki were interviewed about the events of the day of March 11 from 2:46 to the following morning.
