Young Crown Prince Karl Heinrich (Philippe De Lacy), heir to the kingdom of Karlsburg, is brought to live with his stern uncle, King Karl VII (Gustav von Seyffertitz). The king immediately dismisses the boy's nanny (Edythe Chapman) without telling the youngster to avoid an emotional farewell. Dr. Friedrich Jüttner (Jean Hersholt), his new tutor, proves to be sympathetic, and they become lifelong friends. Nonetheless, despite the commoners' belief that it must be wonderful to be him, the boy grows up lonely, without playmates his own age.
