Die unsichtbare Front

Directed by Richard Eichberg

With Karl Ludwig Diehl, Trude von Molo, Veit Harlan, Paul Hörbiger and Theodor Loos

During World War I, Ellen Lange runs away from boarding school to her brother Rolf in Kiel. Rolf, a vice-helmsman, tries to send her back, but she goes to Berlin and finds a job at a music store through “Aunt Jenny.” Her boss sends her to Copenhagen with a false passport to deliver a violin containing stolen papers. In Copenhagen, she meets Erik Larsen, a German secret service agent, and joins the service to atone for her mistake.
