The first episode of Vatigale series is set in Rome in 2013. The capital's anti-mafia investigation department, coordinated by the prosecutor Paola Fasano, in the context of investigations carried out against Nicola Petrillo, an influential politician, randomly identifies the existence of a Masonic lodge inside the Vatican. The incredulity of the investigators is replaced by the amazement when, within the Ordinary Consistory, the Holy Father announces his decision to the world. From that moment the police take an extraordinary character, involving the highest state officials who are not always interested in discovering the truth. The dramatic nature of the events of 1924, man and gentleman.
