The trailer opens with a village official issuing a stark warning to Lib: “It is not your job to question us. You are here only to watch”.

The watch over Anna is to last two weeks, we find out, during which Lib will have to stand watch for eight hours at a time alongside a nun.

“On the fourteenth day,” the officials add, “you will each present your separate testimony.”

When the council tells Lib that Anna hasn’t eaten for four months, she declares it “impossible”.

Nevertheless, she embarks upon her examination of Anna, who defiantly tells Lib that she has no reason to be nervous of fasting as she survives on “manna from heaven”.

Before long, tensions flare between Lib and the local villagers who declare it a mistake to invite an English nurse to care for an Irish child, with dramatic glimpses of Lib carrying Anna on her back down a dirt track and a burning house.
