25 years after the biggest nuclear accident in history, wolves reign the radio-actively contaminated no-man's-land, the so-called exclusion zone, of Chernobyl, which stretches from Ukraine into Belarus and Russia. After the explosion of the Chernobyl reactor on April 26, 1986, one city and some 150 villages were evacuated. About 340.000 people were displaced. Uninhibited by the presence of humans, a profusion of wild species has since taken over a territory of about 3.000 square kilometers, creating a new wilderness. At the top of this eco-system is the wolf.
