Easwaran (Arjun Sarja) is an upright, honest youth who runs a local cable channel in Kumbakonam. He is known to fight for causes of the society and the common man. He enters into fisticuffs with local MLA Poongundran (Sai Kumar) after he exposes his corrupt and greedy ways through his cable TV channel. Fearing trouble, his mother takes him to a saint in Thiruvannamalai. The Swami resembles Easwaran. A sequence of events forces them to swap places. The soft-spoken Swami tries to sort all issues through non-violent means (Gandhian philosophy). Halfway through, Duraisingam (Karunas) dies in the hands of Poongundran and his henchman (Vidharth). In the climax, Easwaran kills Poongundran.

When a young boy Saravanan is killed by rowdy — and aspiring politician — Dhanasekaran (Sayaji Shinde), his distraught mother (Vinaya Prasad) is ready to kill herself. She is stopped by Mani Shankar (Vijayakumar), who promises her that her son will be reincarnated and meet her 30 years hence. The only condition is that the mother must remain inside Vaitheeswaran temple, praying to be reunited with her son. 30 years later, her wait catches the attention of the public, who are curious to see if Saravanan shows up. Dr. Bala (Sarathkumar), who has no belief in reincarnation, wishes to treat her while Dhanasekharan, who is now a politician and eyeing the CM seat, knows that Saravanan’s arrival could derail his plans. Armed with a computer-generated photo of how Saravanan would look like now, Dhanasekharan and Bala go looking for him, when Bala realises that he is indeed the reincarnation of Saravanan. What happens next forms the climax of the story.

Kokki arrives in the city to go to Malaysia for a job with the help of a friend. Somehow, he gets trapped in a situation where a superstitious gangster refuses to free him since Kokki brings him luck.
