Pearl Dubois is a Southern belle. She was born in New Orleans to a prominent and wealthy family. During the Second World War, she wants to help the Allies. She lands a job in Paris working for the Office of Strategic Services. The OSS is the first spy agency in the United States. Its goal is to gather intelligence about the Germans and to win the war.

Pearl convinces her boss to send her on a secret mission. She will bring photos of German spies to General George Patton, who is stationed near the Belgian border. On the way to the general's camp, Pearl and three companions are ambushed by Nazi soldiers. She becomes a prisoner and must survive by her wits until she can plot her escape.

Based on the real-life experiences of Gertrude Sanford Legendre, the first woman to be captured as a spy during WWII, Pearl's adventures are both riveting and inspiring.
