Mean Girls:
A 2004 American teen comedy film directed by Mark Waters and written by Tina Fey. The film stars Lindsay Lohan, Rachel McAdams, Lacey Chabert, Amanda Seyfried, Tim Meadows, Ana Gasteyer, Amy Poehler, and Fey. It is based in part on Rosalind Wiseman's 2002 non-fiction self-help book, Queen Bees and Wannabes, which describes female high school social cliques, school bullying, and the damaging effects they can have on students. Fey also drew from her own experience at Upper Darby High School as an inspiration for some of the concepts in the film. The plot centers on a naive teenage girl navigating her way through the social hierarchy of a modern American high school after years of her parents homeschooling her while conducting research in Africa.

Synopsis:
Cady joins a new public school and befriends Janis and Damian. They warn her to avoid the Plastics, a group led by Regina, but things get worse when she falls in love with Aaron, Regina's ex-lover.
