1831. A village schoolteacher Matthias Spitzbart dreams of the ideal school and writes a textbook on the perfect educational institution. When he becomes principal of a grammar school by chance, he puts his ideas into practice. His almost missionary-like zeal blossoms in wondrous ways, but his family idyll is deceptive. Entangled in his activities, Spitzbart fails to see his wife's affair with pro-rector Mehlmann, daughter Friederike flirts with the trainee teacher, and son Michael's misdeeds are enough to make a mockery of his efforts at exemplary behavior. Teachers, parents and the mayor are of the opinion that he has upset everything that worked before: he is dismissed...

Frank, a tenth grade student, falls in love with his classmate Regine. His father is a well-connected plant manager in the GDR; Regine's mother is a single parent with four children. Regine wants to become a kindergarten teacher, but her grades are poor and she is not allowed to apply for technical college. Frank champions her and seeks an open discussion about these rigid regulations. But his criticism is nipped in the bud.
