One winter's night, a lone figure arrives on foot in a remote Pennine village. The next morning, as the first heavy snow begins to fall, a man's body is discovered in the village churchyard. Anne Tilston, one of three sisters living in a brooding run-down house in the shadow of the church, realises that the dead man is her father, a disgraced former senior police officer long estranged from his family. As DCI Kenny Murrain's team arrive in the village to investigate the unexplained death, a further body is discovered in a nearby field—a young man from the village with no apparent connection to Tilston or his daughters. With the snow continuing to fall, another body is discovered, and Murrain finds himself stranded with his team in the sisters' house with a seemingly motiveless killer waiting outside in the night.
