There is a strike at the spinning mill in Łódź. Among the protesters, Dorota Waltz, the granddaughter of the factory's founder and owner, stands out. Soon, a lawyer arrives from France who, under the terms of the will, makes Dorota the sole owner of the company. As Dorota is not lacking in nerve and cunning, she quickly finds her feet in the role of a businesswoman. She decides to save the factory from bankruptcy at all costs. The lawyer helps her, but not selflessly. He wants to take over the girl's fortune and merge it with his wife's clothing company in France.
