When young Caldera goes down the mountain to the city, he is unusually lucky at first: he finds a job, a friend and a woman. Caldera family buys a house, they have children and life smiles at them. Their misfortune starts when the father, after a work-related accident, loses his job. Then they have to sell their house and move to a shack in the poorest neighborhood in the city. Finally, hunger leads the children to beg. But their father, Ramón Caldera, can not stand that. His pride does not allow him to accept living on alms due to the lost of a job. Desperately, he looks for a way out.
