When Grace Lawson picks up a newly developed set of family photographs, there is a picture that doesn't belong-a photo from at least 20 years ago with a man in it who looks strikingly like her husband, Jack. And though Jack denies it, he disappears that night, taking the photo with him. Now, to save her family from a fierce, silent killer who will stop at nothing to get the photo, Grace must confront the dark corners of her own tragic past.
