Police commissioner Lo Gatto is in charge of the local Italian police station within Vatican State. During an investigation, following the murder of a Vatican priest, he decides to question the Pope! For this reason Lo Gatto is sent to a Sicilian remote island Favignana. There is very little for the commissioner to do on the quiet island, so Lo Gatto decides to investigate the vanishing of a tourist which quickly becomes a very complicated affair.
