Synopsis
The work at the factory is over. The workers went home and the fairy tale began. Screws and nuts, hammer and plane, chisel and screwdriver came to life. "We've done a good job, and now we can have some fun!" said the hammer. The details made such a noise that Samodelkin, who was flying on his all-terrain vehicle, heard it. He offered to arrange a concert and make musical instruments. The work started and finally everything is ready. A fun concert took place and no machinations of defective parts could prevent success.
