As the Black Rose (in France) retrieves a painting from a white-collar criminal, Lubich, the mute Rita is nearly hit by a car. The car's aristocratic passengers, Simone Monterlant and her nephew Fernando Gonzales, hire Nadja to dance at their upcoming masquerade ball. At the ball, Fernando drags her off so two guests (Leonardo Cardinale and his dressmaker friend, Thierry Rothschild) try to make her into an aristocratic young lady before the Black Rose waltzes with her.
