Paul suggests they go for an extreme tour of Pripyat, an abandoned company town which sits in the shadow of the Chernobyl Nuclear Power Plant. Chris is against going on the tour because of the potential danger and would rather stay on the original plan of going to Moscow. They meet tour guide Yuri Dimitri Diatchenko, and are joined by a backpacking couple, Norwegian Zoe Ingrid Bols Berdal and Australian Michael Nathan Phillips. Yuri drives them through the wilds of Ukraine, before they arrive at a Chernobyl Exclusion Zone checkpoint, where they are refused entry by the Ukrainian military. He then takes them to an abandoned checkpoint he discovered years ago.The group stops at a river where Yuri points out a large, mutated fish apparently able to live on land. After arriving in the city, the group is worried about radiation poisoning, but Yuri assures their safety with a Geiger counter. After spending a few hours exploring the abandoned city, Yuri takes them to the upper floor of an apartment building and shows them the Chernobyl nuclear plant on the near horizon. After hearing noises at the other end of the apartment, it is found to be a bear which runs through the hallway past them, but not harming them. ........
