All the broken places

91-year-old Gretel Fernsby has lived in the same mansion block in London for decades. She leads a comfortable, quiet life, despite her dark and disturbing past. She doesn't talk about her escape from Germany over 70 years before. She doesn't talk about the post-war years in France with her mother. Most of all, she doesn't talk about her father, the commandant of one of the most notorious Nazi concentration camps. Then, a young family moves into the apartment below her. In spite of herself, Gretel can't help but begin a friendship with the little boy, Henry, though his presence brings back memories she would rather forget. One night, she witnesses a violent argument between Henry's mother and his domineering father, one that threatens Gretel's hard-won, self-contained existence. Gretel is faced with a chance to expiate her guilt, grief and remorse and act to save a young boy.
