Horse lover Paul Scheibner has dedicated himself to an unprofitable art: The young man wants to become a rider at the Spanish Riding School in Vienna. When his uncomprehending girlfriend Regina leaves him for a nouveau riche hotelier's son, he finds solace with the animal-loving stud secretary Julia. But then his beloved stallion “Maestoso” suddenly falls ill and is to be sold.
