Arun's journey begins at the Thirupparankundram hill, where the Thiruvalluvar statue stands as a testament to Tamil literature. Collaborating with historian Meera, a linguist who specializes in ancient Tamil scripts, he deciphers references to the Thiruvalluvar Stone in a 4th-century Tamil Sangam text. The stone is believed to be a cornerstone of a temple, inscribed with verses from the Thirukkural , the moral and philosophical cornerstone of Tamil thought.
