The small south-west Australian town of Tillbrook has a secret, one that has been kept for over a hundred years. Tillbrook's Dervish Carnival is run by people who are neither human nor animal, but something in between. They live in the woods, and they howl at night...
When journalist David Hampden visits the town with his photographer brother Paul, the secret is threatened. Paul is unknowingly seduced into the world of the Carnies. David must get him back, whatever the cost. But the cost may be both their lives... and possibly even more.
