Muziris, Southern India. AD 72: In an oppressive underground chamber, merchant Jayesh Muziris, the enterprising founder of the most powerful trade empire of Southern India, has just put to rest a legendary fragment of history that, if exhumed, could cause devastation of immeasurable magnitude. Kodungallur, Kerala. AD 2022: Almost 2,000 years later, a team of Indian archaeologists is hunting down clues to locate the site of the ruins of the lost empire of Muziris. Among this group is the rebellious Harveen Gill, who has been doggedly chasing leads for a long time. Things come to a head when she makes a discovery that could perhaps be the key to locating the ancient city. But little does she know that the Vatican is keeping close tabs and this coveted find has put her on a dangerous path.

Rome, Italy. AD 2022: In another part of the world, Donatello Clemente, the soon-to-be-head of Santa Alleanza, a sacred alliance founded to safeguard the interests of the Vatican and the Papacy, is keeping close tabs on the Indian team’s progress, for their next discovery could shake the very foundations of the Church and precipitate the end of the world.

As Harveen continues to unofficially, and unwittingly, lead her team to the very site of this catastrophic sacrament, she sets Don up for a race against time to protect it. But to what lengths will Don, a guardian of the Church, go to fetter the patrons of science? Will Harveen unearth the truth, or will she be forever silenced?
