Florence, modern day.
Multi-talented computer genius Leonardo da Vinci is hired by an Italy-based anti-fraud organisation led by Lorenzo de Medici and his wife Clarice. Seeking to obtain a key code able to break into any data bank in the world, Roman Mafioso Francesco della Rovere has his reluctant son Girolamo sending a bait, the beautiful Lucrezia Donati, to get either Leonardo or his secrets on their side. Thanks to the help of his trusted mole Zoroaster Leonardo gets to dodge this bullet, but the stakes get even higher when Francesco, with the support of the criminal Pazzi family, has Lorenzo’s younger brother killed in an explosive-filled car. Leonardo clearly knows too much and the Romans decide to get rid of him before he is received by the men of the Ministry . But Lucrezia, who unexpectedly fell for the young man, manages to rescue him and have his life saved.
