Heidi is an orphaned girl initially raised by her aunt Dete in Maienfeld, Switzerland. In order to get a job in Frankfurt, Dete brings 5-year-old Heidi to her grandfather, who has been at odds with the villagers for years and lives in seclusion on the alm. He at first resents Heidi's arrival, but the girl manages to penetrate his harsh exterior and subsequently has a delightful stay with him and her best friend, young Peter the goat-herd.
