This is the story of a little girl named Heidi.
She lived in Switzerland more than one hundred years ago.
Heidi is an orphan.
When the story begins, she is only five years old.
Her aunt takes her to live with her grandfather high up on the mountain.
Lower down the mountain is the town of Dorfli.
But Grandfather lives alone and never visits the town people.
Heidi loves living on the mountain and quickly makes friends.
There is a young boy, Peter, who looks after the herd of goats every day.
Peter lives with his grandmother a little further down the mountain, but not as far as the town.
Heidi loves to visit Peter's grandmother.
A day comes, however, when Heidi has to leave the mountain to go live with a sick girl in the city.
She meets a whole new group of people, some are friendly and some are unfriendly.
Miss Rottenmeier, who is in charge of the house, is very disagreeable.
But Clara, the sick girl, becomes Heidi's friend, and Heidi meets her friendly doctor.
Heidi and Clara have some fun adventures, but Heidi never forgets her home on the mountain.
She misses the flowers, the goats, and all her friends.
Will she ever be able to see them again?
Perhaps the friendly doctor can help . . .
