In April 1986, the worst nuclear accident in history happened at Chernobyl in the then Soviet Union. Among others things, this led to the evacuation of a vast area including the city of Pripyat.
Today, the only humans allowed in this zone are military personnel and researchers. This nearly hour long documentary goes into the forbidden zone to study the flora and fauna, especially the wolves.
This is what the Earth may have looked like if the Great Satan and the Evil Empire had clashed. Devoid of humans, the forests creep back slowly, and Nature red in tooth and claw goes about her business unremittingly. The variety of wildlife in this area is amazing, especially larger animals including birds – eagles and black storks.
There is some fascinating footage here including inside several dens of wolf cubs while the mothers were away, presumably hunting for food, and inside a peregrine's nest.
The film crew appear to have spent a whole year in the area, or at least to have returned periodically. While humans are not permitted to live there, other animals from catfish and eagles to wolves and bison seem to have adapted perfectly well, radiation or no radiation. As the narrator points out, the world's greatest nuclear disaster has turned an area once devastated by both two world wars and the excesses of Stalinism into a unique reserve for wildlife.
