When an injured teenager goes missing at a remote bushland campground, local journalist Abby Bardot is determined to expose the area's dark history. The girl bears a striking resemblance to the victims of three brutal murders that occurred 20 years ago and Abby fears the killer is still on the loose. But the newspaper Abby works for wants to suppress the story for fear it will scare off tourists to the struggling township. Haunted by her own turbulent memories, Abby is desperate to learn the truth and enlists the help of Tom Gabriel, a reclusive crime writer. At first resentful of Abby's intrusion, Tom's reluctance vanishes when they discover a hidden attic room in his house that shows evidence of imprisonment from half a century before. As Abby and Tom sift through the attic room and discover its tragic history, they become convinced it holds the key to solving the bushland murders and finding the missing girl alive. But their quest has drawn out a killer, someone with a shocking secret who will stop at nothing to keep the truth buried.
