The scene where two characters have their heads kicked repeatedly is very intense, brutal, shocking and upsetting. They are attacked purely because of the way they dress. Consequently, there is some injury detail and sight of footprint marks on their faces, which is also very upsetting.
A boy who knows about the attack is threatened by one of the attackers that if he tells the police the truth, they will beat him up.
This film is based on true events which occurred in 2007.
The BBC recommends that you should be at least 16 years of age before watching the film, due to the language, violence and upsetting nature of the content.
