The show is a dramatization of the life of Wolfgang Amadeus Mozart beginning from the age of 17 and culminating with his death in 1791 at the age of 35.

The son of King Uther Pendragon, Arthur has no idea about his lineage until he pulls Excalibur from its stone sheath. He takes the throne of the kingdom with the help of Merlin, the great sorcerer. King Arthur finds love with Guinevere, but is oblivious to her romance with Lancelot of the Lake. Meanwhile, Arthur’s half-sister Morgana longs for revenge against him and sets up a conspiracy that drives King Arthur to danger.

The show starts when Colloredo is named successor to the Prince-Archbishop of Salzburg. The new king is an austere authoritarian man which is insensitive to the music of Mozart and allergic to the enthusiasm and the impertinence of the character. For Mozart, Salzburg's life quickly becomes untenable. He was 20 when he decided to leave his hometown with his mother in search of a better future in a European capital. The journey of the composer will be made of failures and cruel disappointments. But at the end, Mozart will experience glory, love, rivalry before its ultimate fall and misery. He left his best work, the Requiem, unfinished.
