Barcelona, 1980s. In a tough urban neighborhood ruled by ex-legionnaires Gandhi, Fontan and Andrade (who are fighting a war for control of the streets), Nen and his friends Palito, Topo and Tostao dream of making it big in the world of rumba. But Nen discovers why his father, El Guacho disappeared many years earlier. He learns how the relationship between his mother, Chata, and Ghandi, leader of the neighborhood, was connected to his father's disappearance, and so Nen is forced to balance his own desire for vengeance with his longing to triumph.
