The story tells
the investigation started by symbolist Robert Langdon and a good-looking cryptologist, Sophie Neveu, around
the murder of a Museum Louvre's curator. In fact,
the unfortunate murdered man was Sophie's grandfa
ther, and
the corpse was found with a series of symbols and
codes, like a pentagram and a Fibonacci number sequence. But police detective Fache will begin to chase Langdon, who escapes after receiving a warning about
the captain's real intentions. Sophie has with her a kind of key with dots and number 24 engraved on it, which opens to her and Langdon a big complex investigation that involves a supposedly heretic
theory: Jesus Christ and Mary Magdalene were, in fact, a couple who produced a daughter named Sara. A millenarian sect called
The Priory of Sion has kept for centuries
the secret of that matter. A masochist and kind of psychopath albino monk, Sibilas, an Opus Dei member, will chase Langdon and Sophie as well, in order to impede that
they solve
the mystery of Christ and Mary Magdalene, and also
the real meaning and location of
the Holy Grail. A passionate British researcher, will help Langdon in his quest, revealing to
them several symbolisms in Da Vinci's master work
The Last Supper, traveling to mythical places in
the UK, such as
The Church Temple, where it is believed that a group of Templars Knights are buried, and Sir Isaac Newton's tomb at Westminster Abbey, where are located some of
the main keys to solve
the Holy Grail's mystery
