In?1984,?a Maltese national treasure went missing from the cathedral of St. John in Valletta - a masterpiece by the legendary Italian master Caravaggio.

Two years of investigations across Europe led to nothing, but a strong-willed priest never gave up. Father Marius Zerafa, director of museums in Malta, managed to establish a channel of communication with the thieves and set off on a quest to recover the priceless painting. Despite not having the money to pay their ransom, he risked everything, putting his life on the line for the sake of a masterpiece.
