A clique of popular girls, all named ""Heather,"" reign supreme at Westerberg High. Veronica is part of their group, but she begins to feel bad about the cruel, unfair treatment the girls impose on ""unpopular"" kids at school. When she meets a James Dean-type newcomer, J.D., she tells him her woes and he suggests they kill off the popular kids, make their deaths look like suicides, and end the tyranny. Veronica thinks he's kidding, but one by one he eliminates these students, who ironically become even more popular once they're dead. After staging a fake suicide, Veronica goes undercover to stop J.D., who's gone over the edge with his plan to blow-up the school, making it look like a mass suicide pact.
