In 1936, foreign correspondent, Nancy Wake, witnesses first-hand the terror of Hitler's rise in Europe. No sooner has Nancy met, fallen in love with and agreed to marry French industrialist Henri Fiocca, than the Germans invade France and force her to take on her first code name of many. The Gestapo call her the White Mouse for her remarkable ability to evade capture when smuggling Allied soldiers across borders. She becomes Helene when she leaves France to train in espionage with an elite special forces group in London. Then, when she returns to France, she is the deadly Madame Andree. But the closer France gets to liberation, the more exposed Nancy - and the people she loves - will become.
