Beautiful. Brave. Dangerous. A woman of many names. The only one who knows how to code messages and becomes the most powerful leader in the French resistance. Because of her unsurpassed ability, the Gestapo is offering five million francs to whoever brings her to them. With that, she enters history as a legend. In 1936, Nancy is an intrepid Australian expat living in Paris. She finds a job as a journalist with her resourcefulness and bluff. In an unusual meeting, where she is infiltrated as a spy, she meets the rich French industrialist Henri Fiocca. After only a few meetings, she soon tames the greatest charmer and seducer of women, Henri, and he proposes to her. Nancy becomes Mrs. Fiocca. In the same year, the Germans invade France. Nancy is the best trained spy who works for the interests of the state and the freedom of the people. It has been given a number of carefully constructed codenames so that it can pass through checkpoints and borders smoothly. She stores the strictest state secrets in the folds of her mind and embarks on a monstrous war that brings sorrow and loss of life and petrifies the human soul. She smuggles people and documents across the border. For her extraordinary ability, she is nicknamed "The White Mouse" by the Gestapo and becomes the most wanted woman. As much as five million francs are offered for her head... Then Nancy is forced to flee France and leave Henri. She undergoes further physical and psychological training with the Special Operations Executive in Britain and is given the code name "Helen". With a mission in hand, she is sent back to France as the deadly Madame Andre and becomes the most powerful leader recognizable by her red lipstick and ferocious combativeness. But no one will be able to protect Nancy if the enemy finds out that the four names she uses are the same woman. And the closer France is to liberation, the more exposed she and the people she loves become.
