Inspired by true events happened in the Terezin Concentration Camp. The story of a deported jazz violinist and his band is set in a surreal imaginary lager. A violinist, deported to the imaginary lager of Siegfriedsdorf, deprived of his violin and forced to work in the carpentry of the camp, transforms a long saw into a strange but fascinating musical instrument. With his obstinate attempts to regain possession of the musical world and alienate himself from the context, he ends up arousing the interest of the German commander who orders him to form a small orchestra together with other prisoners. The violinist is therefore allowed to play again, in a growing approval, but will be forced to keep playing in the dramatic situations that the concentration camp imposes.
