Three high school girls named Heather run an iron-clad, social clique at high school. One of their anointees, Veronica, isn't sure she wants to join them, particularly when she has to snub her old friends. When Veronica meets the new guy at school, she starts pulling away from the clique. At the same time, some of the more popular students start showing up dead with suicide notes.
