Asturias (Spain), 1912: Domingo Ordieres and his four sons work tirelessly in the coal mines. When they manage to save, and after the dramatic death of the father and one of the brothers in gallery eight of the mine, they decide to buy a small exploitation of low-quality coal known as The Madman's Mine. With effort and work, little by little they manage to make a small fortune thanks to the export of coal during First World War. But each brother pursues different dreams: Jandro wants to go to Paris, while Pedro is bound and determined to find coal under the sea.—jsanchez
