On 26 April 1986, reactor number 4 at the Chernobyl nuclear plant exploded, forcing the evacuation of Pripyat and setting off the largest technological disaster in history. This film returns to the site with the people who lived through it: a senior engineer from the reactor's construction team, a hospital maternity doctor, a firefighter who responded to the blaze at unit four, an officer who oversaw radioactive waste removal from the reactor roof, and a woman who was eleven years old when Pripyat was emptied. Interviews are cut with archival footage the survivors kept in their own homes, much of it not previously public, and with scenes of some of them walking back through the abandoned apartments and streets they fled decades ago. Their accounts cover the confusion of the first hours, the physical toll of working near the exposed reactor core, and the long aftermath of resettlement and illness. Framed around the so-called liquidators sent in to contain the disaster, the film stays close to individual memory rather than technical explanation, building its picture of the catastrophe from the ground up.
