Two bourgeois families live in Rome: the family of the "Cavaliere del Lavoro" Antonio Cocozza, owner of a pastry shop, father of Gabriella, and that of professor Giuseppe D'Amore, father of Carlo. Carlo and Gabriella love each other happily, so when they think of getting married they want the two families to get to know each other. While the women make friends, Antonio and Giuseppe immediately begin to fight for anything, and the quarrels continue even when the couple have to choose the wedding dress, the house where to move, the organization of the wedding and reception. Gabriella and Carlo, tired of the constant bickering of the fathers, decide to run away, wanting to scare the parents, to get the wedding at all costs.
