Gunther Erdogan, second violinist of the London String Quartet, plots to steal the manuscript of Beethoven's tenth String Quartet 'The Harp' from the Jagiellonian Library in Krakow, to settle his debts. But Gunther is fed up with playing second fiddle all his life - as well as fortune, he hopes the manuscript will bring him fame - and win the affections of the quartet's new cellist, Jennifer Rose.
