Los violadores del amanecer (1978)
The Dawn Rapists
This film shows a brutal reality in A quite scary way.
A gang of marginalized teens from Barcelona (spain) commit crimes in order to survive, but what they really enjoy is raping females of all ages. The film is quite a shocker and was banned in it's time, today it's still hard to find. The sound track is quite good and helps the film to be even scarier.
Although it's an old school, this film can be used as a great political statement.
Teen Violence, drugs, sex, rape and murder. (IMDB kitie7 )
