Johanna Spyri’s son Bernhard is sick. To entertain him she invents a story about a little Swiss girl, Heidi, who is sent to live with her grumpy reclusive grandfather. She makes friends with Peter the goat boy and brings the old man back to the world. Then her aunt arranges for her to go Frankfurt as a companion to a young invalid, Klara. Heidi helps Klara too, in spite of the comically controlling Fraulein Rottenmeier, but before long the little girl is very homesick. Heidi turns to her creator, Johanna, for help – but Johanna has her own problems as Bernhard’s health takes a turn for the worse.
The Heidi/Johanna story is told over two self-contained family friendly musicals, which can be performed together or independently. Heidi’s origin story is told in a third show, The One True Thing.
