When Bertram Lanz, a developmentally disabled man, goes missing from a local diner, detective Peter Decker is put on the case. Very quickly, he realises there is more to the disappearance than meets the eye when he discovers Lanz's nurse is missing too, and blood is found in her house. Then, while combing the woods, searchers discover the remains of a young man who vanished during a camping trip years ago. Juggling a hot case and a cold case, Decker races to find justice for the families. But as the answers become ever more elusive, he is forced to question if the woods will ever give up their dark secrets - and if these intertwining cases will ever be solved.
