Lancer Spy

An Englishman impersonates an imprisoned German officer and "returns" to Germany to become a national hero. A female German spy is assigned to check him out but falls in love with him.

I Was a Spy

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.
