In the first episode, Lucy investigates four cities and four operas embedded in the cauldron of European politics between the 17th and 19th centuries. She visits Venice, where Claudio Monteverdi invented modern opera with The Coronation of Poppea, the first work which featured real historical characters that the audience could identify with. It is also one of the steamiest and sexiest operas ever written. Then to Vienna, where Mozart's subversive masterpiece The Marriage of Figaro held a mirror up to a society where the Enlightenment was beginning to break down the old feudal order, and Beethoven wrote Fidelio, an opera that embraced the French Revolutionary radical ideals of liberty, equality and brotherhood. Finally, Lucy travels to Milan, where Verdi's Slaves' Chorus in his opera Nabucco captured the hopes and dreams of the Italian people as they moved towards independence and a united nation.
