When a blizzard descends on the coast, Bowditch is called to the isolated home of a terrified couple. A raving and half-frozen man has appeared at their door, claiming his friend is lost in the storm. But what starts as a rescue mission in the wilderness soon becomes a baffling murder investigation.
