1957. Detective Inspector St. John Strafford has been summoned to County Wexford to investigate when a parish priest is found dead in Ballyglass House, the family seat of the aristocratic, secretive Osborne family. The Catholic Church rules Ireland with an iron fist, and Strafford-- a Protestant-- faces obstruction at every turn. There is a culture of silence in this tight-knit community, and Stafford learns the Osbornes are not at all what they seem. When his own deputy goes missing, Strafford must work to unravel the ever-expanding mystery before the community's secrets, like the snowfall itself, threatens to obliterate everything. -- adapted from jacket
