When Chernobyl can be a touristic destination, everything can get bad. Especially at the case of a group of American youngsters who decide to end their holidays in Europe in an alternative way. Two brothers whose relationship is at critical levels, two girls and another couple who participates at the same excursion will witness the absolute terror at the abandoned city of Pripyat, the former home to the workers of the Chernobyl nuclear reactor. When Uri, their operator vanishes, they found themselves alone in the dark as no one else knows their visit there. Maybe the best film with mutants I have seen after the last remake of' 'The hills have eyes'. The dialogs are not winning any Oscar prize, but the action is here, the suspense also. I can't understand why the fans of the crappy 'Paranormal activity' franchise have different opinion at some forums. The work can be done even without paranormal entities.
