The Irish Midlands, 1862 – a young girl stops eating but remains miraculously alive and well. English nurse Lib (Florence Pugh) is brought to a tiny village to observe eleven-year-old Anna. Tourists and pilgrims mass to witness the girl, along with sceptical city journalist Will (Tom Burke), sent from Dublin to expose the ‘truth’ behind the national sensation. Is the village harbouring a saint ‘surviving on manna from heaven’ or is something more ominous at work? A psychological thriller inspired by the 19th-century phenomenon of “fasting girls” and adapted from Emma Donoghue’s acclaimed novel.
