A broken string, fractured echo chamber, rusting valves. 100 musicians meet for four days of rehearsals. They speak different languages. Their instruments are broken. An orchestra of professional and amateur musicians, young and old, set out on a journey against all odds, to a one-time concert. The film traces the creative process from collecting the instruments, to workshops, to three composers and intensive rehearsals, to the night of the performance. Hidden among the cracks, we discover a lyrical and engaging take on the members of the orchestra, on what is broken and whole and on the determined attempt, if only for a moment, to create harmony in a discordant city.
