igh-school teacher Rachel Stark is relieved that her year is almost over so she can leave her obnoxious, apathetic students. Two days before the final day, she sees a light emitting from the face of one of her students. She also sees it on a man on a bus later - who suffers a heart attack and promptly dies. She reassures herself that it doesn't mean anything since the student is fine, but the next day he is reported dead as well. After testing it, she learns that the phenomenon is very real...but has to figure out how to prove it to others when she begins seeing the light on the faces of too many students for their impending deaths to be a coincidence.
