‘I’m not going with you, Aunt Dete!’ Heidi cries.
‘Oh yes, you are!’ Dete answers.
Heidi loves her home in the Swiss mountains, her grandfather, and her friend Peter, the goatherd. So when Aunt Dete takes her away to Frankfurt, she doesn’t leave happily.
In Frankfurt, Heidi is soon good friends with Clara Sesemann, a rich but very ill girl in a wheelchair.
But how can Heidi live without the mountains? And what can she do about Fräulein Rottenmeier, the Sesemanns’ unfriendly housekeeper?
「我不會跟你走的，Dete姑姑！」Heidi大叫。
「你必須跟我走！」Dete回答。
Heidi喜歡她位在瑞士山區的家、她的祖父和她的朋友牧羊人Peter，所以當Dete姑姑要帶她去法蘭克福時，她非常不開心。
在法蘭克福時，Heidi很快就跟Clara Sesemann成為好朋友，她是個富有但體弱多病、要坐輪椅的女孩。
但是Heidi沒有山的陪伴要如何生活？而她又能為Sesemanns那不友善的管家Fräulein Rottenmeier做些什麼？
