In winter, in a small grey city, a choral concert will take place in the theater. The choir soloist is rushing there with all her might. The hall gradually fills up - conversations, smiles, chuckles, grumblings... The audience quiets down only when the choir appears on the scene. Singing makes people weightless and lifts them to unattainable heights. The concert is over, and the quiet life of the city continues, but in a new quality.
