One of several variations of the "Mata Hari" and "Fraulein Doktor" legends, Universal's Madame Spy is set during WW I. Fay Wray stars as Maria, the wife of Austrian diplomat Captain Franck (Nils Asther). What Franck doesn't know is that Maria is a Russian secret agent, assigned to spy on her own husband. Eventually captured and sentenced to be shot, Maria manages to make her escape by crawling through "No Man's Land" -- looking none the worse for wear at the end of her ordeal. A scene-for-scene remake of the German drama Under False Flags, Madame Spy was itself remade (and heavily rewritten) as a "B" picture in 1942.
