Berlin's Tempelhof Airport was opened in 1923 and, under Adolf Hitler, extended to become the world's largest airport which was finally closed in 2008. But even today Tempelhof Airport remains a place of arrivals and departures being used simultaneously as a refugee shelter and a leisure park for the inhabitants of Berlin. A historically unique moment for a portrait of this city within a city, but also of a European society in a state of emergency, caught between crisis and utopia.
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.
