But, as it turns out later, even this "easy" money, according to the laws of the capital, needs to be earned. The guys are helped in this by their neighbors in the house. The former ballerina Elena Sergeevna, who lives on the floor above, knows not only classical steps, but also the capital before the times 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 neighboring apartment.
