After tragic events, orphaned 16-year-old Marla and her younger brother Jack find themselves in the care of their only living relative — a grumpy old man desperately trying to hide the secret of a dilapidated and frightening place in which he has been a recluse for many decades. Forced to leave their home, Marla and Jack venture to faraway lands, across the ocean, to a small, nearly deserted town located in the western part of Scotland, somewhere on the Inner Hebrides. Upon arrival, the children begin to notice unexplainable and frightening things happening in and around their new home. Things the other inhabitants of the island struggle so hard to ignore.
