Paul Winkelmann is the CEO of a successful business in Hamburg that he took over after the death of his father eight years ago. But he is still strongly dominated by his 78 year old mother who cares for him as a child, and who cannot understand why he took an apartment on his own after all these years. The real "problem" starts when Paul gets to know psychologist Margarethe Tietze whose relationship to her parents is also not so easy after all.
"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.
Two old school friends, both in their late twenties. One lives on his parent’s rural estate and does nothing; the other half-heartedly pursues work as a journalist in Düsseldorf.
