Clique of stuck-up girls named Heather rule the high school social scene until the newest member (not a Heather) decides that enough is enough. She and her outlaw boyfriend embark (accidentally on her part, intentionally on his) on a murder spree disguised as a rash of teen suicides. Dense, take-no-prisoners black comedy with buckets of potent slang, satire and unforgiving hostility. Humor this dark is rare; sharply observed and acted, though the end is out of place. Slater does his best Nicholson impression.
