Het geheim van het staal

The Holland National Steel Foundry discovers the secret for the manufacture of a wonderful steel. Piet Goethal, an old workman of the foundry, has two prides, the steel works and his son Joachim. The latter is in love with Maria, the daughter of Alsteen, the local beer-seller, but she refuses to marry him as he has no money. Consequently Joachim falls an easy prey to a foreign secret service agent who bribes him to steal the secret formula. He is disturbed in the act and pursued through the works. To escape pursuit, he tips up a converter, which sets the foundry on fire.
