A Neapolitan tailor, Nennella (Leda Gys), in love with a painter, who has a slender woman named Paquita (Pina Piovani) as a lover, decides to become, in turn, a diva of variety. One evening, he is on stage with his rival, while the painter is in the proscenium box. To disfigure the enemy, Paquita does not hesitate to resort to unfair means and hires a large claque to be applauded and whistled by her rival. A great commotion arises, in which the two women and their supporters take part. Screams, scratches, bites, seats. In the turmoil, the painter is wounded and, transported to Nennella's dressing room, as soon as he comes to, he seals the pact of love with a kiss.
