She may wish it otherwise but now that Sister Agnes is, as Father Julius solemnly teases her, a 'fully paid up' member of the convent, any thoughts that life might go more smoothly with her final vows taken are soon proved mistaken. Outside the oppressive confines of life inside the convent, Agnes is back in her own flat, working at the order's hostel for the homeless. But before long things take a turn for the worse when a young and vulnerable resident, Abbie, is found dead, and the little fragile peace there was is shattered. Though it looks like suicide, questions over what, or who, pushed Abbie to end her life plague Agnes along with questions from her past.
