An intense study of how obsession can not only destroy the person concerned but those around the person. A stern, particular violin teacher, Anna (Nina Hoss) becomes fixated on the success of one of her pupils at the expense of her family life, from acclaimed German actor Ina Weisse who co-wrote the script with Daphné Charizan.
It all starts at the school’s annual entrance exam, and despite the opposition of the other teachers, Anna promotes the admission of Alexander (Ilja Monti), a boy in whom she detects a remarkable talent. Her relationship with Philippe (Simon Abkarian), her charming, violinmaking French husband, with whom she has a 10-year-old son Jonas (Serafin Mishiev), is in slow decline.
Besides the brilliantly acted drama, the violin concertos are extremely well orchestrated. Hoss carries the film just as well as a violin virtuoso captures an audience. Director Weisse steers the intensity a terrifying climax.
