The distinguished physicist Dr. Vetra is found dead, with a mysterious symbol engraved with molten metal on his chest. At the research center in Switzerland, the scene of the horrific murder, the famous professor of symbology Robert Langdon is called in to unravel the mystery.

The symbol he encounters confronts him with a terrifying possibility: the resurgence of a powerful secret brotherhood, the Illuminati. Langdon fears that this move merely signals the beginning of a sinister plan, aimed at the ancient enemy of the brotherhood, the Catholic Church.

His fears are confirmed on the eve of the Conclave meeting, when a messenger from the Illuminati delivers a nightmarish message: the placement of a bomb in the heart of the Vatican. It is then that Langdon, with the help of physicist Vittoria Vetra, will embark on a relentless quest to discover, through crypts and catacombs, abandoned temples and hidden mausoleums, a 400-year-old path filled with ancient symbols, stretching throughout Rome and leading to the lost lair of the order: the only hope to thwart the explosive plan and save the Vatican.

Dan Brown's first thriller featuring protagonist Robert Langdon. A unique blend of thrilling adventure and sophisticated intrigue, combined with the sharp humor found in the novels of the top author, set against the eternal battle between science and religion.
