In the new film adaptation of Johanna Spyri's popular children's book, Heidi is sent to live for a short time with her eccentric grandfather, the "Alpöhi", who lives alone above the village and initially wants nothing to do with his granddaughter. Heidi's friend Peter, the baseball-playing son of an engineer from Boston, helps her out and shows her how to write e-mails. A little later, Heidi has to go to her aunt Dete in Berlin. Her grumpy daughter Clara, a lonely city girl, dyes Heidi's hair blue and not only causes the bath to overflow, but also Heidi's patience. Heidi wants to go back to her grandfather. Doris, a girl from a Berlin internet café, and 327.80 marks bring this dream within reach.
