Set in The Irish Midlands in 1862, the story follows a young girl who stops eating but remains miraculously alive and well. English nurse Lib Wright is brought to a tiny village to observe eleven-year old Anna O'Donnell. Tourists and pilgrims mass to witness the girl who is said to have survived without food for months. Is the village harbouring a saint 'surviving on manna from heaven' or are there more ominous motives at work?
