The unveiled treasures in the year of the Extraordinary Jubilee. The Papal Basilicas of Rome seen as never before: St. Peter's, St. John in the Lateran, St Mary Major, St Paul Outside the Walls and the works of art enshrined within them. A film tour shot from previously unseen points of view with the latest-generation 3D and 4K technology.

Season two's storyline picks up right where season one left off: with the 44 B.C. assassination of Gaius Julius Caesar and the near-simultaneous death of Niobe, wife of Caesar's faithful bodyguard Lucius Vorenus. Diverted from his post after learning that Lucius, his assumed grandson, was in fact Niobe's illegitimate son, Vorenus now descends into near-madness over his failure to protect Caesar, his role in his spouse's death, and the rumored murder of his estranged daughters.
