Teachers are selecting new pupils at a music-focused high school. A violin teacher Anna Bronsky convinces her colleagues to give a chance to Alexander, in whom she sees a remarkable talent. She is determined to prepare him for the decisive exam. Focused only on her new student, she neglects her son Jonas and her husband Philippe. The pressure mounts and with her harsh behaviour Anna is trying to fix the mistakes of her career. Come the day of the exam, events take a tragic turn.
"Actress Nina Hoss embodies a woman who is trapped in her own rules so compellingly that the whole film becomes as strained as a string of a violin. You are watching her with both – pleasure and fright. This role brought the actress "Silver Seashell" in San Sebastian Film Festival." (Mantė Valiūnaitė)
