Policarpo De Tappetti is a calligrapher who works under the orders of Don César Pancarano de Rondò. For many years, Policarpo has been seeking a promotion and a raise that never comes, and, it seems, will never come. One day, Jerónimo, the son of Don César, meets Celeste, the daughter of Policarpo, and falls in love with her. Policarpo sees in that relationship the solution to his aspirations at work, and does everything in his power to make this relationship fruitful. Don César, who presumes to be a count, sees with very bad eyes that his son meets a girl from such a different social position, and does just the opposite. But the efforts made by both parties will be of no use, since Celeste has fallen in love with Mario Marquetti, a "specialized mechanic" (typist) who is giving private lessons in the offices of the businessman Franquinet .
