Plot summary: what THE DAYS is about
THE DAYS is a Japanese drama that revisits one of the most serious industrial emergencies of the 21st century: the crisis at the Fukushima Daiichi nuclear power plant after the Great East Japan Earthquake of 2011. The series opens as a massive earthquake and the tsunami that follows strike the coast and cripple the plant. Inside, the people on duty must respond to a situation no training fully prepared them for.
The story moves between the control rooms on site, the headquarters of the power company and the officials trying to make sense of events from afar. Radiation cannot be seen or heard, and every decision has to be made with incomplete information and little time. The workers also face a public that is divided. Some people look for someone to blame, while others see courage in those who stay at their posts.
The series is based on true events and draws on published accounts of the disaster. It focuses on the human pressure behind the headlines rather than on spectacle. The question in the tagline, “What happened there on that day?”, sets the tone for a sober and tense look at the aftermath.
