Documentary about the special friendship between the 72-year-old music machine collector Johann Bartisch and the 12-year-old farm boy Gerd from the village of Arnsgereuth. As a child, the Romanian Johann played "O sole mio" on the piano while his brother accompanied him on the violin. Even then, he was fascinated by the music machines that could be found at fairgrounds, in cinemas and on trains. As an adult, Johann began his passion for collecting in Bucharest, rescuing self-playing instruments from barns, cellars or even garbage dumps. With great attention to detail, Johann restores his found treasures in his 250-year-old schoolhouse in the village of Arnsgereuth.
