Bully

Lyla finds a great friend in Jamie on her first day of school, but when Lyla joins the cheerleading squad and a clique of popular girls invites her to join them, Jamie is left behind. Lyla knows bullying when she sees it though and when she sees her new friends viciously teasing classmates on facebook, including Jamie, she realises that she doesn't want to be friends with such people and is smart enough to leave the clique. These girls don't take kindly to anyone rejecting them or their ideas though and they are soon out for revenge.
