Bound by the secrecy of confession, the pastor tries to identify the owner. When the crucial lead takes him to Tuscany, he decides to take a vacation with his differently-abled sister and elderly grandparents. Together with tourism agent Giulia Franca, who works part-time at a fish restaurant, he discovers a severed hand with a fish symbol on the beach. Suddenly, they all find themselves entangled in a dubious Catholic organization. A beautiful location on the Tuscan coast becomes the setting for a sophisticated game of intrigue within the Catholic Church.
