The film features strong language ('motherf**ker', 'f**k') as well as uses of 'shit', 'asshole', 'bullshit', 'son of a bitch', 'damn', 'Jesus' and 'God'. There is sustained threat throughout when a group of hikers are stalked, attacked and imprisoned by a village full of people who live in a forest. There are scenes of sexual violence in which a woman volunteers to sleep with a man rather than be murdered. In a scene of horror, men and women who have been blinded and starved are briefly shown feasting off a dead body.
