The story of a young nun who, one night on a deserted beach, meets an old fisherman who is desperate because of the poor catch. Suddenly, a miracle occurs, leading him to believe that she is the Virgin Mary, while she exploits the man's blind faith to leave her convent forever. It is a story that speaks first and foremost of faith in the broadest sense of the term, that is, believing in something at all costs, but also of the desire for revenge and emancipation.
