London, 1953. Thirteen years have passed since England surrendered to the Nazis and formed a Grand Alliance with Germany. It was forced to adopt many of its oppressive ideologies, one of which was the strict classification of women into hierarchical groups based on the perceived value they brought to society.

Rose Ransom, a member of the privileged Geli class, remembers life from before the war but knows better than to let it show. She works for the Ministry of Culture, rewriting the classics of English literature to ensure there are no subversive thoughts that will give women any ideas.

Outbreaks of insurgency have been seen across the country with graffiti made up of seditious lines from forbidden works by women painted on public buildings. Suspicion has fallen on Widowland, the run-down slums where childless women over 50 have been banished. Rose is given the dangerous task of infiltrating Widowland to find the source of the rebellion before the Leader arrives in England for the Coronation ceremony of King Edward VIII and Queen Wallis.

Will Rose follow her instructions and uncover the criminals? Or will she fight for what she knows in her heart is right?
