I Was a Spy

Directed by Victor Saville

With Herbert Marshall, Conrad Veidt, Madeleine Carroll, Edmund Gwenn and Gerald du Maurier

During World War I, a young nurse in a hospital in German-occupied Belgium is secretly feeding military information to the British. Complicating matters is the guilt she feels when she has to treat the German casualties inflicted as a result of the information she's passed on, and the fact that the local German commandant is falling in love with her.
