Seaside adventurer Artyom, who came from the Mineral Waters of Maga, an aspiring blogger from Kazan, Naila, and an intelligent Kaliningrad woman, Varya, accidentally become owners of a rather large amount of money, which literally falls on them from the wall of a legendary high-rise in the center of Moscow. But, as it turns out later, these "easy" money must be earned according to the laws of the capital. The children are helped by their housemates: former ballerina Elena Sergeevna, who lives on the floor above, knows not only classical steps, but also the capital before the time of Moscow City, a young British man in love with Russian culture who rents a room in the same house, as well as young guys from Tajikistan who are doing repairs in the next apartment.
