Sister Bernard has lived in a grey-stone convent in rural France for more than seventy years. In that time, a once youthful and lively cloister has gradually emptied, until only Bernard and two other nuns remain. Now, the three women pack away their few possessions into wooden boxes, preparing to leave the building that has been their home for decades.
For the nuns, the closing of the convent means more than losing a home; the walls have shielded them from a changing modern world, for Sister Bernard the quiet monotony of the religious life has protected her from memories of the past - the disgrace of when she was a young woman in wartime France; when her devotion to God faded in the face of her need for a young Nazi soldier; and when she experienced the full horror and violence of war.
