Florina lives in a valley in the Swiss Alps with her mother, father, and brother Ursli. One day, while walking in the mountains, she finds a tiny bird that has lost its mother, and Florina takes the bird home to care for it. The girl and the wild bird soon become best friends. She makes food for it using her doll's tea set and gives it a special basket for a bed.

When the bird grows up, its wings grow larger and it wants to fly. Florina must decide whether to keep the bird or release it to fly back tp the mountains.
