A plucky little orphan girl gets dumped abruptly into her gruff, hermit grandfather's care, then later gets retaken and delivered as a companion for an injured girl.
Heidi is orphaned and her selfish maternal Aunt Dete takes her to the mountains to live with her grumpy old paternal grandfather, Adolph Kramer. Heidi brings her grandfather back into mountain society...through her angelic ways and sheer love. When Aunt Dete steals Heidi away to be the companion of a rich man's invalid daughter, the grand-father is enraged and sets out to get her back.
