Once upon a time, Andrey went against the family tradition and, abandoning his career as a teacher, went to Moscow. The business failed, and the only way to fix things was to sell the family house, which, according to rumors, Pushkin once lived in. But there is a problem: in order to make a deal, it is necessary to obtain the permission of the father, who is serving time in the colony and blames his son for this.
