In 1875, Mauricio Sargal, libertine and bon vivant, an Antillean millionaire returned to Spain, is obliged to go back to Cuba when he finds out his sister, Dulce, has disappeared.
To discover what has happened to her, he will have to face his brother-in-law in Siboney: a fugitive from justice who has managed through the years, at the cost of all his scruples, to assemble the greatest fortune in the whole of the Spanish Empire, from the mother country to its overseas possessions.
