A painfully shy high schooler, crushed between merciless classmates and a fanatically religious mother, discovers she can move objects with her mind just as adolescence awakens the power within her. A cruel prom-night prank becomes the spark that ignites her long-buried rage into an inferno of telekinetic vengeance. Brian De Palma adapts Stephen King's debut novel with feverish style, split-screen bravura and an unbearable slow build toward catastrophe. Anchored by Sissy Spacek's fragile, terrifying performance, it is a landmark of seventies horror, a tragedy of cruelty and isolation that erupts into one of the genre's most unforgettable finales.
