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.

Ten-year-old Fiona is sent to live with her grandparents in a small fishing village in Donegal, Ireland. She soon learns the local legend that an ancestor of hers married a Selkie – a seal who can turn into a human. Years earlier, her baby brother was washed out to sea and never seen again, so when Fiona spies a naked little boy on the abandoned Isle of Roan Inish, she is compelled to investigate.
