On the brink of a breakdown, Jim Hawkes quits his high-powered job and rents a cottage in the Devon countryside, seeking some much-needed rest. But Slyford St James is far from the peaceful haven Jim was hoping for. Almost immediately he is plagued by strange occurrences - a combination lock that won't open, loud noises in the attic, the figure of a little girl always just out of sight - and he soon discovers the house he's staying in was the site of a terrible tragedy. But as Jim is haunted by the ghosts of the past, he also finds himself endangered by a real-world threat in the present. It soon becomes apparent that true evil lurks within.
