What Lies Beneath begins with Claire (Michelle Pfeiffer) and Norman Spencer (Harrison Ford), a seemingly happy married couple who have just sent Claire’s daughter off to college. Now an empty nester married to a busy scientist/professor, a bored and listless Claire comes off as lonely and maybe a little desperate for attention.
When new neighbors Mary and Warren Feur move in next door in their lakeside Vermont neighborhood, Claire becomes convinced that Warren is abusive and has killed off his young wife.
