Their only child, Caitlin, is leaving for college as the movie opens. Claire now has to deal with empty nest syndrome. Except that the nest is not quite as empty as it seems. Claire starts to hear things. Doors open before she touches them.

It's an accumulation of little things that just don't seem right, enough to unnerve her, quite possibly enough to threaten her. There's little that hasn't been done before, but there's a reason that it's been done before - it works. Meanwhile, the Spencers have new neighbors, the Feurs. Claire thinks there is something amiss next door. In a clear Rear Window reference, she spies on them and is convinced that Mr. Feur killed his wife and that Mrs. Feur's ghost is haunting their house.
