The first Ukrainian animated film in color and sound. The animals make an agreement - to work and live in peace. Their "League of Nations" is joined by a fox who, having lulled the vigilance of his neighbors with the sweet melody of the barrel-organ with a picture of a dove of peace on it, insidiously breaks the agreement. One of the film's directors, Ipolyt Lazarchuk, became the "father" of the Ukrainian animation school in the post-war period.
