After a bad losing streak, Lisa Freyberg wants to sell her inherited horse stall. Trainer Roberts, however, is successful in making the stall profitable again. Lisa's new passion for horses, however, is proving to be a losing streak for her engagement to her estate neighbor Thermalen. She's hoping for a new victory with her horse Arabella and has the apprentice Otto bring the horse to the competition in Dresden. Otto, however, takes the train to Dresden with his first love, Ossi la Planta and leaves the job to the grooms. But neither the horse nor the grooms show up in Dresden!
