The action takes place in the 18th century in Lima. The wandering artists Pericola and Piquillo perform in the town square. They love each other, but cannot get married - the poor artists do not have the means for this. Meanwhile, the Viceroy of Peru, Don Andreas-Ribeira, likening to Harun Al-Rashid, dresses up as a commoner and goes out into the city to find out what his subjects say about him. He falls in love with Pericola at first sight. But the fact that she is not married prevents the Pericole from appearing at the royal court.

A mysterious man under the name Mister X performs in the circus, playing violin on a chair suspended in the air by ropes. His breathtakingly sad melodies reflect his internal turmoil - he's in love with a noble lady and this relationship is frowned upon in their society.
