To get a break from a stalled career as a Hollywood screenwriter, Rowan retreats to an isolated cabin in the Adirondacks with her fiancé, Seth. There in the wilderness, Rowan finds herself drawn to a local mystery --- that of the infamous socialite-turned-feminist-crusader Eddie Callaway, who vanished in the same woods 40 years earlier and was never heard from again. A handbook found in the abandoned ruins of the Callaway camp gives Rowan a glimpse into who Eddie was --- until a fateful discovery begins to unravel what might have happened to her. As Rowan draws closer to the truth, she realizes that the past, and the Adirondacks woods, may hold two keys: one that reveals what really happened to Eddie Callaway and another that unlocks a future beyond her wildest imagination.
