Regular girl, Veronica (Winona Ryder), tries to survive the social jungle of high school by sticking with the three most popular girls at school who are all called Heather. As she meets a sociopath named JD (Christian Slater), her life spirals into a continuous cycle of hate and unintentional murder, as she exacts revenge on her enemies, AKA her best friends. Dark, cynical and subversive, this cult classic gently applied a chainsaw to the conventions of the high school movie -- changing the game for teen comedies to follow.
