After the death of Alexey Gradov, the owner of a large construction holding company, his heirs enter into a struggle for a billion-dollar fortune with a former official and business partner of the deceased. On the family side, the war is led by Gradov Sr., the patriarch of the family, who founded the family business in the 90s, but retired. As an ally, he takes the financier and strategist of the company Nadezhda, who was not only a colleague, but also his son's mistress. In addition to the redistribution of assets, the Gradovs — wives, children, grandchildren — are busy identifying old grievances and accumulated claims against each other. They have everything—money, power, connections, status. But that's not enough for them. In the pursuit of inheritance, they are ready to tear apart not only the enemies of the family, but also each other.
