After the death of Aleksey Gradov, the owner of a large construction holding, his heirs enter the struggle for a billion-dollar fortune with a former official and business partner of the deceased. From the side of the family, 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 claims that have accumulated against each other. They have everything - money, power, connections, status. But this is not enough for them. In pursuit of an inheritance, they are ready to tear apart not only the enemies of the family, but also each other.
