Secrets of the Vatican reveals the culture of a Vatican few outsiders have seen, plagued by corruption, cover-ups and ruthless power struggles.

Using undercover footage and interviews with Vatican insiders, as well as abuse victims, whistleblowers, and journalists, Secrets of the Vatican also shows the deep sexual hypocrisy within the Catholic Church and the long legacy of clergy sexual abuse of children.

“Unless you spend some time inside this kind of culture, it’s very hard to believe that it could be like this,” journalist Robert Mickens tells FRONTLINE.

How did the Vatican get to this point? Just how far does the corruption extend? Is there hope for meaningful reform? Can Pope Francis take on the entrenched interests in the Vatican bureaucracy? Is he really going to try?

We’ve asked Secrets of the Vatican filmmaker Antony Thomas and co-producer Jason Berry and to join us for a live chat to answer those questions and take yours.

They’ll be joined by guest questioner Elizabeth Dias from TIME magazine. Elizabeth recently co-wrote TIME’s Person of the Year portrait of Pope Francis.

You can leave a question in the chat window below, and come by at 2:30 p.m. ET on Feb. 26 to join the live discussion.

We’d like to thank TIME for partnering with us on today’s chat.
