In 1958, Cullymore is the type of small Irish town where everybody knows your name. So why does it suddenly feel full of strangers? Golly Murray, a well-liked Protestant wife and mother, finds herself wishing a violent death upon Blossom Foster. Blossom, in turn, feels totally unlike herself while she flirts with Golly’s Catholic husband, Patsy. Father Hand, the town’s revered priest, can’t get his mind off Father Patrick Peyton, an Irish priest who hosts star-studded galas in America. And James Reilly, once a beloved teacher in the local Catholic school before he ignited a scandal, has moved to a tiny shack by the lake, where he spends his days plotting the murder of Father Hand.

Who can save Cullymore from the townspeople’s darkest desires? Father Hand calls together the “great old Cullymore gang,” an aging group of Catholic friends, to put on an Easter play. Their performance could put this tiny border town on the map. As strife between the local Protestants and Catholics heats up, a sinister narrator, all-seeing but unseen to the souls he manipulates, decides to make his presence known, once and for all.
