Dusk 2010 on netflix

After a group of teenagers discover one of their friends lying dead on a river bank on one of the hottest days of summer, a story of jealousy, insecurity and peer pressure gradually unfolds. Group leader Caesar is able to magnify – out of all proportion – the small grievances that each of Jessie’s friends bear towards her and transforms them into a general and pervasive hatred that leads ultimately to her horrible, senseless killing.
