In this supernatural thriller, a woman believes that a visitor from another dimension is trying to guide her into a sinister mystery. Feeling lonely after her daughter leaves home for college, Claire (Michelle Pfeiffer) begins to sense that something is wrong in her house, and feels a spirit is trying to contact her. At first her husband Norman (Harrison Ford), a scientist doing research in genetics, attributes her paranormal beliefs to stress or possibly a nervous breakdown, and sends her to a psychiatrist (Joe Morton) who puts no more stock in Claire's stories than does Norman. While Claire's contention that someone or something sinister is afoot leads her down a number of blind alleys, in time she becomes convinced that the mysterious happenings at her home are somehow connected to the disappearance of a woman who was a student at the nearby college -- and bore a striking resemblance to Claire. What Lies Beneath marked the debut of screenwriter Clark Gregg, whose script is based on a story by himself and Sarah Kernochan; the supporting cast includes Diana Scarwid as Claire's best friend Jody, and James Remar and Miranda Otto as a contentious couple living next door.
