Tormented (2009)

The fat, plain-looking Darren Mallet (Calvin Dean) committed suicide at a high school in the UK. His death did not make much waves at school, as the bad boys who bullied him continued to have fun, singing and dancing, while beautiful and academically excellent students like Justin Fielding (Tuppence Middleton), the president of the student union, were concerned about the improvement of relationships and the coming of love. In the school, it seems that only Jensen Banks (Olly Alexander), a good friend of Marlet, is really sad for his friends. At the party that followed, the high school students had a lot of fun. While they were getting carried away, they both received threatening text messages from Marlette's mobile phone. That night, a student was brutally killed in the graveyard. The group of students thought it was Jason's prank, but the successive tragedies showed that everything was by no means so simple.
