A group of young tourists (Ingrid Bolsø Berdal, Jonathan Sadowski, Devin Kelley), hoping for an adventure off the beaten path, hires an extreme-tour guide. In spite of warnings, the tour guide takes the sightseers to the town of Pripyat, Ukraine, once home to workers at the nearby Chernobyl nuclear power plant but abandoned after the 1986 nuclear disaster. After briefly exploring the ghost town, the tourists find themselves stranded -- and worse, they are not alone.
