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.
Unfortunately the movie Mister X is not yet available on Disney Plus.
