Inspired by the true story of World War II heroine Nancy Wake. At the age of sixteen, Nancy left her native Australia to find a new home and the love of her life in Marseille. However, during the Nazi occupation, she could not stand aside and, as the increasingly famous and especially elusive White Mouse, became a thorn in the side of the German forces. When she was discovered, she had to flee to England, while her husband Henri was detained by the Gestapo. However, Nancy does not give up - after hard training, she returns to SS and Gestapo-infested France to help liberate her new home and her beloved Henri... The gripping story, based on real events, brings the fate of one of the bravest women of the last century closer to life.
