There is no school on the mine site. Teacher Gábor Nagy is enthusiastic about the organisation. The chief engineer Laskó, on the pretext that there are not enough children to open a school, ruins his whole job, has his men throw the benches out of the engine room, which has been converted into a classroom, and chases the children away. The teacher, however, does not give up the fight and, together with the miners, continues to fight for the school. Eventually, all the problems are solved, new families arrive on the site, whose children have reached the required number of children and can continue their education.
