The miners' rebellion

Madrid, 1933. Tristán Valdivia leaves the capital to return north. There he is awaited by his father, owner of the Northeast Mining Company. Out of the blackness of the Asturian mining valleys emerge luminous characters, and beneath the deafening noise of the coal mines the whisper of an ancient song is heard. Old and new times brutally collide to test the protagonist, and soon the entirety of humanity.
