Brothers of the kobza workshop go to the forest in search of a tree from which you can make a kobza. The picture shows all stages of production of Ukrainian traditional musical instruments. In the process, there is the daughter of one of the brothers, Nastunya, who lost her voice when her mother died, and for a long time she only mumbles her songs. When the brothers finish their work, they go to a concert dedicated to the ATO soldiers. A miracle happens during the concert - Nastun's voice returns.
