Jon Pearce is the only police officer on two small islands off of the coast of England; a beautiful and popular tourist spot during the high season, but cold and desolate during the winter months. He finds himself in over his head after a series of unexplained incidents leave various islanders terrorised, and against his better judgement, he is forced to call in Ed Thorn, a renowned paranormal investigator.

Together, Ed and Jon discover that the victims of the paranormal incidents are suffering terrible consequences, specific to their own worst fears, and are being left in circumstances that are excruciating to bear.

They must enlist the help of Dr Dina Melnyk, a lecturer in Occult Studies and an old friend of Ed’s: she thinks she might know what it is that plagues and threatens them – and it is worse than they ever could have imagined – but not necessarily how to destroy it. Can they find who unleashed the evil entity and discover how to stop it before it reaches the mainland?
