Louise Basset works as a housemaid at The Ritz Hotel, home to the most powerful Nazis in France. As she changes silk sheets and scrubs sumptuous marble bathtubs, she listens and watches, reporting all she can to the Resistance. The only secret she never tells is her own. Everything changes for Louise when a young Allied pilot, hunted by the Nazis, is smuggled into the hotel. She feels her heart begin to open. But what might happen if Louise finally confides in someone? Years later, her granddaughter Nicole looks up at the ornate façade of the infamous Paris hotel. She is reeling from her recent discovery: a black and white photograph of her grandmother as a young woman, head shaved, branded a traitor. Devastated by her new legacy just as she's about to start a family of her own, Nicole begins to search for answers.
