When world-renowned Harvard symbologist Robert Langdon is summoned to a Swiss research facility to analyse a mysterious symbol — seared into the chest of a murdered physicist — he discovers evidence of the unimaginable: the resurgence of an ancient secret brotherhood known as the Illuminati.  It is the most powerful underground organization ever to walk the earth. The Illuminati has surfaced to carry out the final phase of its legendary vendetta against its most hated enemy, the Catholic Church. Embarking on a frantic hunt, Langdon follows a 400-year old trail of ancient symbols that snakes across Rome toward the long-forgotten Illuminati lair - a secret location that contains the only hope for Vatican salvation.
