Anna Bronsky is a violin teacher at the Conservatoire. Against the advice of her colleagues, she imposes the admission of a pupil, in whom she sees a great talent. With a lot of involvement, she prepares Alexander for the end-of-year exam and neglects her young son Jonas, who is also a violinist and ice hockey fan. She moves away more and more from her husband, so fond of him, the French 'luthier' Philippe Bronsky. At the approach of audition, Anna pushes Alexander towards performances more and more exceptional. The decisive day, an accident occurs, heavy consequence.
