Damaged but not yet broken after his ordeal in Tasmania's wilderness, 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.

But when a crucial witness and a policewoman disappear, it's clear that a disciple of the Falls' dark history is on the loose.
