Based on the hunt for the Beast of Exmoor, multi story have created a hugely entertaining 'mockumentary'. In the winter of 1982 scores of sheep were savagely slaughtered on Exmoor. A Beast was on the loose. The Marines were called in. Amateur hunters joined the fray. Press-hounds bayed across the moor. Beast! considers our need for monsters and what happens as we hunt them. The hunter becomes the hunted and hero and beast are in danger of becoming indistinguishable. Myths from around the world are evoked as supporting evidence. Hercules and the Lion, Diana and Acteon, Beowulf and Grendel - even the Werewolf of Ilfracombe - they all make an appearance along with the Marines and other assorted victims and hunters.
