A little boy, Kostya Buikov, lives in a cottage outside a big city with his mother, father, and a parrot named Pedro. His parents work a lot, so an elderly nanny, Aunt Izolda, often looks after Kostya. Behind the Buikovs’ cottage, surrounded by the Great Forest, there is a place hidden from the world: the Abandoned Dacha with a Little House—where Kostya is strictly forbidden to go. That’s exactly why, whenever he gets the chance, the boy runs off to that very Abandoned Dacha, which he rightfully considers his Command Center-For-Games.
One day, heading to the Command Center on very important business, Kostya discovers that unexpected guests have moved into the Little House. No, not stray dogs. And not even neighborhood hooligan boys.
The Abandoned Dacha has been claimed by a family of trolls. And it seems these trolls have absolutely no intention of leaving Kostya’s territory.
