Orphaned as a baby, Heidi lives with her Aunt Dete, but when the latter gets a new job that means she can no longer keep the little girl, she is only too happy to dump Heidi on her reclusive, grumpy old grandfather, a goatherd who lives high in the Swiss Alps. Despite the worries of everyone in the village about leaving the girl there, the odd couple-after some initial reluctance on grandfather's part-are happy together. Away from her aunt's oppression, the little girl's spirits soar, and her goodness and faith soften the old man's heart. Playing with the goats and Peter the goatherd, and sleeping nestled in the hayloft in her grandfather's cabin, Heidi is happier than she has ever been. But then Aunt Dete reappears and persuades Grandfather that the position she has found Heidi in Frankfurt as a companion to a wheelchair-bound girl, Clara, is for her own good and will help her to get on in life. Although Heidi learns to love Clara, the servants-particularly the cold-hearted, stern Fraulein Rottenmaier-make her unhappy, and she desperately misses the mountains, until a friendly doctor realizes the cause of her sleep-walking and intervenes.
