Dawn in Madrid. In the Plaza de la Cibeles begins the daily grind. The statue of the goddess, from its source in the center of the square tells the story of a man, petty speculator, owner of an old building that is going to ask Saint Nicholas for his cooperation to make it sink, and thus be able to lift a twelve-story modern building. But the inhabitants of the block have also implored the Saint to prevent this from happening.
