An utterly gripping and emotional World War II tale inspired by the incredible true story of Noor Inayat Khan, the first female radio operator sent by SOE into Nazi-occupied France.

Paris, 1940. As Nazi soldiers march down the Champs-Élysées, Noor's heart is shattered. Her family is forced to flee their home to the safety of England, and as Noor watches the French coast disappear in the distance, she vows to do everything she can to stop Germany from devouring her beloved country.

Training as a wireless operative in England, Noor's perfect French makes her the ideal candidate for undercover work in her beloved Paris, and she is soon assigned to an illustrious spy network led by a mysterious man named Prosper.

Day after day, Noor walks the treacherous streets of Paris looking for safe places to broadcast messages to London. But Nazi officers lurk around every corner, and Noor's heart thunders in her chest as she evades detection. She knows it would take just one stop and search for her life to be over.

With each passing day, her mission becomes more lethal as, one by one, her fellow agents are captured. Someone is betraying them, but who? And when Noor becomes the last agent in the network, can she keep the links with England alive to help win the war?
