Jude Law and Diane Keaton star in this drama that was created and directed by Paolo Sorrentino. Lenny Belardo, aka Pius XIII, is the first American Pope in history. Young and charming, his election might seem the result of a simple and effective media strategy by the College of Cardinals. But, as we know, appearances can be deceptive. Especially in the place and among the people who have chosen the great mystery of God as the guiding light of their existence. That place is the Vatican and those people are the leaders of the Catholic Church. And the most mysterious and contradictory figure of all turns out to be Pius XIII himself. Shrewd and naïve, old fashioned and modern, doubtful and resolute, ironic, pedantic, hurt and ruthless, Pius XIII tries to walk the long path of human loneliness to find a God for mankind. And for himself.
