With their sights set on a �25,000 reward promoted by a local newspaper, American documentarians Georgia and Matt head to Exmoor in North Devon to film the fabled beast supposedly slinking through the remote terrain. Is the creature a leopard, a panther, a family pet crossbreed, an imaginary predator? Setting up a forest camp with an old acquaintance harbouring his own dark secrets, the trio fix 42 cameras to the trees and rocks, linked back to a computer nerve centre where nothing should go unnoticed as they take turns to night watch. But then they discover some putrefying body parts all neatly tied up� then some more. And before long they realise they are in the lair of a beast right enough, but certainly not one of the four-legged variety. For they have discovered a serial killer�s playground and are soon to become his most wanted prey.
