Popular high school senior Virginia Wainwright (Melissa Sue Anderson) survives a freak accident, but suffers from memory loss and traumatic blackouts. As she attempts to resume a normal life, something terrible is happening - her friends are being ruthlessly murdered one by one. But will she be the next victim or is she the killer? Veteran director J. Lee Thompson's classic shocker was made during the period before the horror genre drenched itself in irony and self-reflexivity, and instead revels in the effective staging of terrifying set-pieces which drive its towards a terrifying climax.
