1948 post-war Moscow. An unknown dance group enters the stage of the Hermitage summer theater. 14 young collective farmers in little dresses with birch twigs in their hands. As soon as they start to move, the audience literally freezes - what happens on stage is amazing! The girls seem to be floating above the wooden floor. And it is completely incomprehensible how they manage to do it ... The next day, all of Moscow talks about this miracle. And in a few years, the whole world is talking about them! So the legendary band "Brzoza" appeared.
