In a vanished age, when Nature was revered as a divine force, the venerated Neelakanda Nayanar had guarded an ancient secret, the revelation of which would bring catastrophe to the world.
Cut to the present, a cult-like body of powerful personages is in covert pursuit of the elusive secret to establish their Lord as the Supreme one in the world.
The ancient secret that sets off a chain of momentous events transforms the lives of three millennials; Nilagriva Chandra Shekhar, Sindhoora Vaidyanathan, and Jeeva Velu Stane. Armed with a set of mystic hymns and a piece of relic, they race ahead of time to protect their family, land, and love. Traveling from Chennai to Chidambaram, they try to discover the reason that pits man’s greed against his own survival.
Meanwhile, in a village called Pandayanilavur (Land of Ancient Moon), an age-old transgression that calls for vindication is threatening to destroy Nilagriva’s family. Will he be able to stop them before it is too late?
Spanning several centuries, journeying across the state of Tamil Nadu, and drawing on the aura of an ancient secret, the story is a mix of mystery, mythology, relationships, and the age-old battle of good versus evil.
