The story follows Guido Quiller (Celentano), a billionaire engineer who has grown incredibly wealthy by inventing a type of indestructible, burglar-proof glass. This invention has made him the enemy of the criminal underworld—specifically the family of Tilli (Eleonora Giorgi), a talented pickpocket.

After a series of accidents leaves Quiller temporarily unable to speak or identify himself, he is found and taken in by Tilli’s family. Believing him to be a fellow petty thief, they embrace him. Quiller, instantly smitten with Tilli, chooses to maintain the charade. To impress her and fit into her world, he begins "staging" robberies—often using his own money to pay off the victims or stealing back his own property—resulting in a "twisted Cinderella" plot where the prince must pretend to be a pauper to find true love.
