What Lies Beneath (2000)

It had been a year since Dr. Norman Spencer betrayed his beautiful wife Claire. But with Claire oblivious to the truth and the affair over, Norman's life and marriage seem perfect--so perfect that when Claire tells him of hearing mysterious voices and seeing a young woman's wraithlike image in their home, he dismisses her mounting terror as delusion. However, as Claire moves closer to the truth, it becomes clear that this apparition will not be dismissed, and has come back for Dr. Norman Spencer... and his beautiful wife.
