In 1910, the great Russian author Leo Tolstoy (CHRISTOPHER PLUMMER) is in the final year of his life, and he is being pulled from all sides as to whether he will leave the publication rights to such great works as "War and Peace" and "Anna Karenina" to his wife, Sofya (HELEN MIRREN), or to "the Russian people." As leader of the organization that preserves and distributes Tolstoy's books and philosophies, Vladimir Chertkov (PAUL GIAMATTI) pushes hard for the latter as it would secure the Tolstoyan Movement's finances for decades.
Chertkov, though, must deal with the force of nature that is Sofya Tolstoy, who has learned over the years how to use her mood swings and grand emotions to manipulate her husband and those around her into doing her bidding. Sofya, of course, is angling for the publication rights to secure her and her children's futures. She does not adhere to Tolstoy's central beliefs that wealth should be distributed and material possessions and financial security are inherently evil and corrupting.
Chertkov has managed to sway Sofya's daughter, Sasha (ANNE-MARIE DUFF), to his side. He even goes so far as to place a loyal member of the movement in Sofya and Leo's house as a spy. The man's name is Valentin (JAMES McAVOY), who agrees to serve as Tolstoy's secretary and is so dedicated to the cause that he has taken a vow of celibacy in its name. But his willpower is challenged by Masha (KERRY CONDON), a sexually aggressive fellow Tolstoyan who has a different take on the great author's works and teachings.
