In 1575, the future Marquis of Dénia, Don Francisco Gómez de Sandoval, decides to get to know the town in depth with Jaume, his loyal servant. Both, carried away by the impetus and the desire for adventure, are involved in a love affair that will mark the destiny of the young heir.
Meanwhile, in Naples (Italy), the Cervantes brothers, Miguel and Rodrigo, after serving a ten-year exile, embark on the galley Sol with hopes of a better future in their country.
Years later, in 1609, the sinking of a galleon off the coast of Denia will take with it secrets of both in which, four centuries later, in 2009, a young diving teacher, German's descent, will find an answer. The fortuitous discovery of the remains of the galleon will put at stake the development of a budding love affair and will make those who have been dragged by ambition, greed, and jealousy risk their last breath of life to possess the coveted treasure.
