The film starts with the demise of CM (Satyamoorthy), a political plot produced by R. K. Boopathi (Prakash Raj). Then, we are introduced to Kamalakannan (Karthi), who tells his story to auto driver Rajini Appadurai (Santhanam (actor)). Rajini assumes that Kamal is rich and drives him around the city to be profited for him. Kamal is actually a country boy who is working in a small company. He has come to the city to meet concerned politicians and plead them to halt a subway project, by which he could lose his property in his village. He is the son of a humble person who serves unlimited food to the guests and passersby every day. Under this background, he has come to Chennai to settle the matter as the forefather’s property is living heaven for the family. Kamal stays in his aunt Rani’s (Roja (actress)) house, and love blossoms between him and her daughter Sridevi (Pranitha Subhash). Their love affair breaks up as it is not accepted by Rani. Kamal meets Boopathi, who once visited their village during the election campaign and had promised to do good needs when required. Kamal comes to know that Boopathi is the one behind the project. Kamal later makes Ramani (Raadhika) the Mayor of Chennai by helping in her campaigns. He later, in a jail, gets the contact of Perumal (Kota Srinivasa Rao), who has an infamous political party. Meanwhile, he joins Perumal's party and makes him win the election, making him the CM of Tamil Nadu. Boopathi is finally arrested for being the reason behind for Sathyamoorthy's suicide with his family. Kamal, at last, saves his property with his intelligence and unites with Sridevi.
