During World War II, women of all backgrounds work as spies: Krystyna Skarbek, the Polish aristocrat whose daring exploits earn her the title of "Churchill's favorite spy," Andrée de Jongh, the Belgian girl whose ambitious escape network will save hundreds of Allied airmen, Josephine Baker, the glamorous singer whose fame provides the perfect cover for her anti-Nazi activities, and brothel owner Kitty Schmidt, whose Nazi-run establishment offers both secrets and pleasures.
Stoic Vera Atkins was determined to build a network of female agents, Virginia Hall made a daring escape from France, Mathilde Carré was a treacherous double agent, Noor Inayat Khan was a Muslim princess turned fearless radio operator, young mother Yvonne Cormeau sought revenge, and Yolande Beekman was a young artist turned spy. Amid covert operations, betrayal, and mounting danger, they defy the odds, each demonstrating unparalleled courage - and some paying the ultimate price.
