In 1910, famed novelist Leo Tolstoy (Christopher Plummer) and his wife Sofya (Helen Mirren) vehemently disagree over the rights to Tolstoy's literary legacy. Sofya believes her husband should bequeath them to her upon his death, while Tolstoy's chief disciple, Chertkov (Paul Giamatti), has nearly convinced the writer to sign the rights over to the Russian people. To this end, Chertkov inserts a spy into Tolstoy's household, who promptly falls for one of the novelist's daughters.
