Peter Bang, a journeyman carpenter who knows absolutely nothing about horses, wins the trust of Toni—a mare that had broken loose—and gently leads her back to her stud farm. There, he is offered a job as a stable hand, as he clearly possesses a special knack for handling horses. Peter accepts the offer but notices that the jockey, Otto Burian, treats the mare rather roughly. Believing that Otto’s colleague, Hans Rückert, has a better way with horses, he secretly arranges for Hans to train with the mare.
