Rose (Maeve Higgins), a mild-mannered driving instructor living a quiet life in the Irish countryside, has a gift for communing with restless spirits. Yet she renounced her ghostly profession after being implicated in a tragic exorcism-gone-wrong. When a widowed father (Barry Ward) seeks out her services to perform an exorcism on the pestering ghost of his dead wife, she reluctantly agrees to help—but things get complicated when a has-been American singer (Will Forte) targets the customer’s teen daughter for his own nefarious purposes. Sly humor and outright goofiness are intermingled with real feeling and occasional flourishes of supernatural gore in this unabashedly charming modern-day fairy tale.
