Issachar and Zabulon, two brothers in their twenties, are supremely stupid and never bored, as madness is part of their daily lives. When they lose their mother's beloved dog, they have 24 hours to find it - or she will kick them out.
After long years spent in exile in Paris, Lyubov, a strange and elusive woman, returns to her ancestral estate, about to be sold to pay off the family’s debts. As the centre around which the play revolves, forever oscillating between tragedy and comedy, this maternal figure, this mater dolorosa, played by Isabelle Huppert, returns to a family unsettled by the future of the estate, and more largely, by that of this world she left behind. Modern society, with its social changes, is right around the corner, noisily announcing its arrival.
