Benvenuto Cellini, the great Florentine sculptor, is sentenced to hang, but he is pardoned when the duke realizes that he has not completed a previously commissioned sculpture. Freed, he is able to turn his attention to his favorite model (and object of his affections), Angela. The Duke also is interested in Angela. Thus, Cellini does his best to keep the Duke away from Angela. Meanwhile, he finds he has to keep himself away from the Duchess! At the end of the show, Cellini escapes yet another death sentence by fleeing to Paris.
