University professor Mondrian Killroy is adored by his students; his most popular lecture is the one known as Lecture 21, in which he discusses the genesis of Beethoven’s Symphony No. 9. However, professor Killroy has disappeared and only Marta knows where to find him. She wants another chance to hear him give his eccentric lecture, Lecture 21, where he questions the importance of the aging composer’s late work. As conceived in Marta’s mind, a dream-like story unfolds about the young violinist Hans Peters, whose frozen body was found not far from Vienna in 1824, the year Beethoven’s Ninth was performed for the first time. This young man, who died gripping the neck of his violin so tightly that he had to be buried with it, is portrayed in the film as a passionate defender of his Master’s music. On the snowy plains, where he later meets the Angel of Death, Hans passes a series of bizarre characters representing period thought and opinions, and also the musicians with whom he was rehearsing Symphony No. 9. The film, the directorial debut of writer and essayist Alessandro Baricco, features performances from a string of remarkable actors.
