Two families live in an old house in a small town. Downstairs with his parents, a poor boy and upstairs, the owner's little girl, who sings very well and aspires to become a great singer. The boy adores his little friend and is very proud of her pretty voice. One day the children go to a fair together. The boy buys his friend a gingerbread heart with his hardly saved pennies and gives it to her out of great love. But he cannot yet tell her how much he loves her. He whispers his feelings only to the old willow tree, which is the only one who knows his secret. The years pass and the children become adults…

Two brothers - foundlings - are in the service of a rich landlord who has two beautiful daughters. While the younger is not only beautiful but also good, the older is pride and envy itself. So when the brothers encounter a she-wolf while shepherding and she gives them miraculous gifts, the older sister does everything she can to rob them of them and the happiness they can bring. Little does she know that the she-wolf is an enchanted princess who will not only marry one of the brothers, but also justly punish her wickedness.
