North Germany in the 1920s. At their stud farm on the lake, close to the Baltic Sea, Carl von Edzards is a successful racing thoroughbred breeder. He has passed on his great love of horses to his daughter, Charlotte, who dreams of one day continuing the work of her father. However, such desires are not considered proper for a daughter of a good family and instead their son, Hans, is intended to take on the management of the stable. Nevertheless, Charlotte’s mother is eyeing up a good match for her: Richard, the only son of a respected and rich ship-owning family. Only one thought occupies Charlotte’s mind: how can she avoid marrying this man who she does not love? Then by chance she discovers why her parents are so emphatically insisting on this marriage.
