But sinister letters with leaves are arriving in the mail, rekindling the same crazed paranoia that destroyed her life before. When a cold case involving a local man's mysterious disappearance suddenly re-opens, police begin searching around a majestic oak tree on Jolene's property. With her secret past threatening the loss of her family forever, she resorts to a twisted tale of lies and deceit to conceal what happened that night. But Jolene can obsess about nothing else: Someone knows. Had there really been a figure standing in the shadows that night, a witness to Jolene's crime? Or is the real danger the darkness within her own mind?
