Iván Berend works with all his skills in the coal mine he inherited from his father. Fate brings him to fall in love with the beautiful Evila, the daughter of one of the miners. A wealthy Viennese banker, Félix Kaulmann, then buys up the Bondavölgy coalfield for money, but he cannot acquire Iván Berend's mine for the time being. To defeat his opponent, he comes up with a cunning plan. He takes Evila with him to the Austrian capital, then opens the new mine, luring Berend's best colleagues to him with a little more money. But he doesn't count on one thing.
