Juan does not have a penny, but he lives wonderfully. Their nights of revelry and cabaret are famous in the nocturnal circles of the city. As heir to his elderly and wealthy uncle don Patricio, he is subsidized by his creditors on account of the future inheritance. But Juan keeps a terrible secret: he has long been disinherited. When a telegram arrives announcing the death of the uncle, Juan returns to the family home on the Catalan Costa Brava. There he meets Ana, a wonderful woman, who is the current heiress of the family fortune.
