This film is set in a medieval mill town in the Harz mountains. The greedy and brutal millman and his accomplices, the castle steward and the mayor, set fire to a forest mill that the farmers used for processing their grain. Without their mill, the farmers must now rely on the millman's services. When the farmhand Anna uncovers the millman’s crimes, he swiftly detains her and a young miller, Jörg. The forest spirits have a different plan, however, and they free the young couple with the charge to rebuild the ruined forest mill and turn things around for the villagers.

"Spring Symphony" is the story of Robert Schumann and Clara Wieck. Both were music entities. Robert Schumann turns out to have been a second tier composer, if that, never rising to the heights of a Beethoven or Mozart. In contrast, Clara Wieck was a master technician in the playing of the piano, a composer (probably not at Schumann's level), and was a child prodigy.

The Prinz-Eugen-Gymnasium is in a crisis, which is not least due to the insolent students who lack any respect for the staff and the chaotic principal.

At the same time, a new student joins the group, the smart checker Jürgen, who immediately falls in love with Karin, the kitchen assistant at the local snack bar. Chaos soon breaks out...
