A deliciously nasty black comedy, Heathers is set at a cliquish high school in Ohio. The most exclusive of those cliques is the Heathers, comprised of the prettiest and most popular girls in town. The group's leader is the manipulative Kim Walker, who orchestrates the humiliation of anyone who fails to meet her standards. Eventually, Heathers member Winona Ryder begins to exhibit a conscience; together with her hardcase boyfriend Christian Slater, Ryder plots to avenge all the unfortunate victims of the group. Before long, Heather (Kim Walker) ends up dead along with Kurt and Ram, with poignant suicide notes posted near their bodies.
