Nightingale Man

During World War I, Luke is recruited by the British Secret Service from the American pilots flying with the French Air Force. His mission is to rescue Nurse Edith Cavell, captured by the Boche, imprisoned in German-occupied Belgium and doomed to be shot as a spy. All too-soon it becomes a challenge to stay alive. Who's double-crossing him? Can it be the English gal he's falling in love with? Or is it the Spy-master back in England who's set him up as the fall guy?
