Igor Kostin was one of the main witnesses of the Chernobyl catastrophe. On April 26 1986, several hours after the explosion, he flew over the plant; the radioactivity was so high that all his films turned black. Only one single picture survived: it was shown around the world. For 20 years Igor has lived with the 800,000 liquidators' and continued to photograph the plant and the forbidden zone around it. His story became the story of Chernobyl. For the first time he tells this story in words and in pictures.'
