The Good Word(2014)

Ivan Cutler is a man on a mission - he spreads the good word throughout the town lands of Ireland in the 1950s. But he hides a sinister secret - he has a penchant for murdering those who are kind enough to invite him into their homes. However, when he calls to the rural farmhouse of Ma and Da Taggart, he meets two people who prove more than a match for him.
