Bremen, 1891. Udo Jürgens' grandfather Heinrich strolls thoughtfully about the Christmas market. For days, the young man has suffered a momentous decision: should he emigrate to America or seek his fortune in Moscow? The touching performance of a street musician playing a Russian song on his bassoon gives him an unexpected decision-making aid. Henry sets off for Russia - and thus begins a fateful story that spans three generations and two world wars.
