A year ago, Dr. Norman Spencer (Harrison Ford) betrayed his beautiful wife Claire (Michelle Pfeiffer). But the affair is over and Claire's oblivious to the truth; Norman's life and marriage seem perfect--so perfect that when Claire tells him she's 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.
