Based on the book by Claire Keegan, the setting is the small Irish town of New Ross in 1985. The title sequence immediately gives us the theme of the story - a rotating skyline of the town, dominated by one point, the local church.
Bill Furlong (Cilliam Murphy) runs a coal merchants, drive the lorry round the town to make deliveries, before returning to his wife and five daughters. He's a well known, well respected member of the community, treats his staff well, although his wife reckons he's a bit "too soft". One morning he goes to make his delivery at the convent and finds, locked in the coal shed, a terrified young woman, begging him to take her with him. He takes her in to the sisters, who fuss over and take her quickly away, then leaves. But her fear remains in his mind.
Furlong has to decide. Between the safety of acquiesence, as advocated by his wife (and given added persuasion by the Mother Superior). Or the risk of becoming a social pariah, if he follows his conscience. More information about the convent becomes obvious. It is one of the infamous 'Magdalen Laundaries', where young women, pregnant and unmarried, are used as slave labout before thier babies are sold to childless families. A practice that continued well into the nineties.
These are the kind of nuns that give penguins a bad name. This a society still in the grip of the church, which nefoces social convention and dictates who is unacceptable within the town. The tension, the sense of oppression, is well conveyed, even as the town celebrates Christmas. Murphy is excellent as the quiet man wrestling with the biggest decision he has ever faced, knowing that if he does the 'right thing' it will go badly for him and his family. Knowing that standing up to this kind of evil has consequences well beyond himself.
It might be set in the past, but it feels so recent, with TV programmes and cars that many of us can still easily recall. It is still very relevant, for that kind of oppression has many forms, and the fascist verion is looming over us so much nowadays. A poerful reminder of the need to stand up to evil.
