Alexander Goldin is a great composer, although he himself does not yet know it, and in general he is afraid of a large audience. In order to understand that his music is worthy of being heard from the stage, he has to move into a certain mysterious world, where bird cherry torments allergy sufferers all year round, and terrible muds rattle on tin cans. These ignoramuses consider piano music to be a real cacophony, and even the wise mountain hermits Eyo, who settled next to the Talking Echo, cannot convince them otherwise... But colorful poodles in this city, where people adore dogs, will help the musician find his calling and his love, and at the same time will throw up many dangerous and funny adventures... But will Alexander be able, will he want to return to the familiar world?..
