The Da Vinci Code (2006)

Jacques Saunière, a Louvre curator, is pursued through the Grand Gallery by an albino Catholic monk named Silas, who demands the location of the Priory’s “keystone” to find and destroy the Holy Grail. Saunière gives him a false lead and is murdered. The police find his body posed like Da Vinci’s Vitruvian Man. Police captain Bezu Fache has his lieutenant, Jérôme Collet, summon American symbologist Robert Langdon, who is in Paris for a lecture on the interpretation of symbols, to examine Saunière’s body. Langdon is shown the body and a secret message, readable only by blacklight. It contains an out-of-order Fibonacci sequence. Sophie Neveu, a police cryptographer and Saunière’s granddaughter, tells Langdon that Fache planted a tracker on him after finding the words, “P.S. Find Robert Langdon” at the end of Saunière’s secret message. Fache believes that Langdon murdered Saunière. Sophie throws away the tracker, distracting the police while they sneak around the Louvre, finding more clues in Leonardo da Vinci’s works. Langdon deduces that Saunière was the grand master of the Priory of Sion.

Silas works for an anonymous person referred to as “The Teacher”, along with members of Opus Dei, led by Bishop Aringarosa. Langdon and Sophie travel to the Depository Bank of Zurich and access Saunière’s safe deposit box by using the Fibonacci sequence. Inside is a cryptex, a cylindrical container that contains a message on papyrus. It can only be opened without destroying the contents by turning dials to spell a code word. As police arrive, bank manager Andre Vernet helps Langdon and Sophie escape, then attempts to steal the cryptex and murder them. Langdon and Sophie escape with the cryptex. They visit Langdon’s friend, Sir Leigh Teabing, a Holy Grail expert. Teabing claims the Grail is not a cup but instead is Mary Magdalene. He says she was not a prostitute but the wife of Jesus Christ. Teabing argues that Mary was pregnant during His crucifixion, and the Priory formed to protect their descendants.
