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 Alamelu (Sudha) takes him to a saint in Thiruvannamalai. Guruji 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 Poovarasu (Vidharth). In the climax, Guruji kills Poongundran.
