Cass is building a new life for herself and her young son Ben after the death of her soldier husband Pete, returning to the village where she lived as a child. But their idyllic new home is not what she expected: the other flats are all empty, there's strange graffiti on the walls, and the villagers are a bit odd. And when an unexpectedly heavy snowstorm maroons the village, things get even harder. Ben is changing, he's surly and aggressive and Cass's only confidant is the smooth, charming Theodore Remick, the stand-in headmaster. Not everyone approves of Cass's growing closeness to Mr Remick, and it soon becomes obvious he's not all he appears to be either
