Pope Francis' first year as pontiff

Pelley speaks to President Obama and the pope's closest friends, including a rabbi he's known for years in his native Argentina, who describe a pontiff who is surprising the world by spurning tradition to bring humility and humanity to the papacy.

In addition to the U.S. president, Pelley talks to Rabbi Abraham Skorka, who befriended him in his native Argentina and shares his passion for soccer. Another personal friend, Elisabetta Pique, an Argentinian journalist whose children were baptized by the future pope, also appears. Pelley interviews Robert Mickens, an American known as a "Vaticanista," an expert journalist who has covered the Holy See for many years.

One of the new cardinals hand-picked by the new pope will also weigh in. Cardinal Gerald Lacroix of Quebec City, Canada, gives Pelley some insight into the critical ways the new pope is changing the status quo and addressing sex abuse in the Catholic Church.
