Dominic Corde is thrilled to "fill the robe" as substitute vicar in the village of Cottisham, while the Reverend Wynter is away on a three-week Christmas holiday. Glad to escape his dreary London flat and a less-than-satisfying job as church curate, Dominic and his beloved wife, Clarice, set off for what they hope will be a lovely winter getaway. Upon arrival, in the midst of a frigid, exceptionally snowy season, Dominic and Clarice are welcomed by warm, hospitable neighbors and enchanted by the cozy, inviting vicarage. Everything seems almost too perfect. Dominic's only concern is how he will be received by the congregation, who hold the Reverend Wynter in such high regard. But as Clarice soon discovers, she and Dominic have much more dire matters to worry about. It turns out that the Reverend Wynter isn't on holiday at all--and that something very sinister has transpired.
