A peculiar family, which owns a nougat factory, decides to set out on a trip to Madrid in order to advertise its products in a Food Fair. Besides the disapproval from the family head and company founder, events are not as expected.

The love of a young woman, Dolorcitas (Ana Giner), descended from a less aristocratic family is disputed by her husband, an enterprising entrepreneur, Melchor Llorens (Leopoldo Pitarch), and by an old and young suitor, Daniel Soler (Ramón Sernequet), a young man with a cradle and a waste of family wealth. This one through the blackmail puts the name of the young woman in question. The festival of Moros y cristianos, in which both are captains, will serve to unmask the young man, save the girl's name and redo the happiness of his marriage.
