Kazimierz Wajda

When teenage Krysia's father dies and her aristocratic, cold-hearted grandmother tries to force her to live with her, two well-natured tramps rescue her and take care of her the best they can.

Two friends, Szczepko and Tonko, are made unemployed in a toy factory where there was a ban on singing and they broke the rule. In a park they find a abandoned baby, and they take it into their care. Meanwhile, Wanda, owner of a toy shop, comes to Lwów with her uncle. He wants his niece to work for the director of this factory. By coincidence, the child is given to Wanda. Szczepko and Tonko look for him desperately. But the uncle is more and more happy about having the child.
