Anna O’Donnell (Kíla Lord Cassidy) is an 11-year-old girl who claims not to have eaten for four months, surviving miraculously on “manna from heaven."

As Anna's health rapidly deteriorates, Lib is determined to unearth the truth, challenging the faith of a community that would prefer to stay believing.
