Two people are kidnapped and wake up chained in a dirty basement. A voice over a speaker tells them they must play games to escape, with escalating stakes like cutting open an eye to find a key, or be killed by a bear trap. The police follow clues to the house but find it empty, with the victims dead, as the trailer hinted at the kidnapping but not the outcome. The film proposes a horror/thriller about an evil man who torments and kills victims as revenge for past misdeeds.
