Parisian sisters. Fiona Valpi

Paris, 1940. The city occupied by the Nazis seems to have changed forever. But for three girls, workers of a sewing workshop, life is still ongoing. Each of them carefully preserves his secrets: Mireille fights on the side of resistance, Claire secretly meets with a German officer, and Vivien is involved in a case whose details cannot reveal even to the closest friends.

After a few generations, the granddaughter of Claire, Harriet, returns to Paris. She desperately wants to reunite with the past of her family. She has yet to find out the truth that will be much worse than she imagined. By bit, she will restore the story of courage, friendship, stamina and fidelity. The history of ordinary people who are forced to commit unusual actions in harsh wartime.
