Das Mädchen Marion (alternatively known as Preis der Nationen) is a German Heimatfilm that premiered on 26 October 1956.
Before he dies as a consequence of stress from fleeing the stud farm, Kalweit entrusts Marion von Hoff with the newly born Trakehner foal Prusso, for whom he predicts a bright future in equestrian sports based on his pedigree.
Along with the other refugees and with a heavy heart, mother and daughter leave their home and flee with Prusso and their most valuable possessions in a cart as the Second World War reaches its end.
As she makes a chance glance out a window, she suddenly sees the sort of close relationships that has developed between her mother and Dr. Meining.
The next morning as Prusso and Legler face the formidable Berndella ridden by Lieutenant Ortega, Marion sends her horse and her new love off with the Trakehner saying: “Show your courage, Trakehner-blood!” In a thrilling race, Prusso and Legler prevail in the international competition over Berndella und Ortega.
