Diego and Patricia, two “professionals” in the illegal art trade, are hired by Jaques Roman, a French millionaire, for a special job: to steal the Codice Calixtino, a 12th century manuscript kept in the cathedral of Santiago de Compostela, whose history and power have attracted pilgrims for over a thousand years.
Despite the historical and financial value of the Codice, poor security allows Diego and Patricia to carry out their task without a hitch. But the Codice is much more than a pilgrim’s guide. Among its pages, hidden by a medieval technique, lies the gospel of Saint James the Elder, one of Christ’s favourite disciples. This reveals information about Jesus’ genealogy that could destroy the faith of all Christendom, as it goes against the creed: it denies the divinity of Jesus and his eternal union with the Father, it denies the Trinity, it denies the virginity of Mary and, as if that were not enough, makes her the mother of a line of men and women sharing Jesus’ blood.
For the Vatican this gospel is the book that announces the apocalypse and it puts all its money and power behind the mission to destroy it.
