From all appearances, Mackenzie Phillips seems to have a good life; three great kids, a beautiful wife, lovely home—nothing seems amiss. But, when Mack takes the kids for an overnight camping trip, what starts out as a fun getaway soon turns into a parent’s most horrifying nightmare—his youngest daughter, Missy, is abducted from their campsite and her body is never recovered. As Mack struggles to make sense of such enormous tragedy, he descends into a “great sadness” where his life starts to unravel and all the ghosts that he thought he had buried long ago, resurface and push him to the edge of a precipice. It is at this time, at his darkest hour, that Mack receives a mysterious note in his mailbox with an invitation from God to meet at the shack—the place where Missy’s bloody dress was found. In a desperate attempt to find closure and answers to his daughter’s murder, Mack heads back into the Oregon wilderness to confront the killer or God…or both.
