In 1964, young Julia Welling is sent to Bavaria to create and manage a home for children. For the past of her father (a member of the Nazi party) Julia now defends the values of democracy and wants children to be treated like whole persons. Her first days in Bavaria are difficult because the people are very conservative: when she notices some parents beating their children, she steps in and they don't understand her intervention. She meets a young American officer who is organizing the end of US occupation forces in Germany; he helps her get a former military installator for her new children's home. She manages to install the home and begin her activities, but one night a violent farmer tries to burn down the building because she has protected his son.

A few leagues from Seldwyla, in the Zurich countryside, two children, Sali Mantz and Vreneli Marti, form an inseparable pair of playmates. Unfortunately, their farming parents, who have always been friends, are at odds with each other over the purchase of an adjoining field.Sali and Vreneli don't see each other again until much later and fall in love, but their parents still hate each other fiercely. Despite everything, the young couple will try to live their forbidden love.

Two 11-year olds, Julia and Martin, decide to swap lives with each other.
