A making-of experience to discover how a program filmed in the dead of night, within the walls of the Vatican, was created. It took a long, painstaking process, following Alberto Angela through the various set preparations, the filming phases, the preparation of the guests, and the work of all the technicians. St. Peter's Basilica, the Vatican Museums, the necropolis of Santa Rosa, the Apostolic Palace, and the marvelous gardens are just some of the places where the RAI Naples team shared the complexities of filming, tiptoeing among the treasures hidden within the high walls, thanks to the collaboration with the Vatican Television Center.
