Der Weg zu Isabel.

The German estate owner Corner travels to Marseilles, looking for his daughter. He had a relationship with a French aristocrat before the World War and knows she was pregnant, when he had to return to Germany. The War separated them however and the mother died giving birth to his child. He knows neither the name of his daughter, nor where she is living. A lawyer named Beauchamps is tasked with finding her and one days introduces a young singer named Isabel to him. She is with great probability the one, who is being sought. She follows her father back to Germany, but only with great reluctance.
