Damaged but not yet broken, park ranger Taylor Bridges believes his ghosts are in the past - until a raging forest fire in an isolated canyon of The Falls lays bare the remains of a young woman… and a decade-old killing ground.
After the police enlist Taylor in their investigation, the evidence bizarrely points to a deranged preacher who reigned over The Falls a century ago.
