In 1987, PM Rajiv Gandhi announces the re-creation of Local Self administration bodies in india, and the plans for elections. "Maniakkarar" Rajamanickam (Prabhu) is a rich landlord in a village in Tanjore. His pregnant step-sister Kayavarnam (Viji Chandrasekhar) approaches him with a request that he should not contest the upcoming election for Village Chief, as her husband wants to contest. Rajamanickam relents without thoughts, and his sister goes happy. Meanwhile, leaders of 8 villages gather with Rajamanickam, and convince him to contest, as the Village Chief post will be contested by many people with wrong intentions if Rajamanickam doesn't contest. Rajamanickam agrees with the villagers, and asks his brother-in-law to withdraw. His brother-in-law vehemently refuses and the election heavily contested. Rajamanickam wins with a high vote difference and his brother-in-law hangs himself. Kayavaram portrays the suicide as heart attack, and promises revenge on Rajamanickam, effectlively severing their relationship.

In 2010, Vetrivel (Sasi Kumar) is a organic-fertiliser vendor, who lives in a nearby village with his parents (Ilavarasu and Renuka) and brother Saravanan (Ananth Nag). Saravanan falls in love with his classmate Subha (Varsha), the only daughter of Rajamanickam. Meanwhile, Vetrilvel develops a liking for an agriculture researcher Janani (Miya).

Vetrivel urges his father to approach Rajamanickam with a marriage proposal between Saravanan and Subha for which Rajamanickam opposes citing caste differences. Vetrivel and Saravanan plan to kidnap Subha during a temple festival but the plan fails as they accidentally kidnap another girl Latha (Nikhila Vimal) by mistake. Latha is engaged to Arul (Rajesh), son of Kayavarnam and her wedding was supposed to take place in a week. Vetrivel realizes his mistake and rushes back to the village to drop off Latha but her father commits suicide before her arrival thinking that Latha eloped with someone. She understands that it was Kayavarnam who behaved very rude towards Latha’s father which made him to end his life.

Vetrivel marries Latha as she is helpless now. Vetrivel’s parents accept Latha understanding her situation. Janani although disappointed, understands Vetrivel’s situation and accepts his decision. Meanwhile, Rajamanickam plans to get his daughter Subha married to his relative but Vetrivel interferes and cancels the wedding talks. Finally, Rajamanickam decides to get Subha married to Arul with the hope of ending his long dispute with Kayavarnam. The wedding is arranged and Rajamanickam drops off Subha in Kayavarnam’s house fearing Vetrival’s intervention again. But Rajamanickam finds out that Kayavarnam has plans to ditch Subha after wedding as a means of revenge on Rajamanickam.

Rajamanickam understands his mistake and meets Vetrivel and agrees for Subha's wedding with Saravanan. On his way back, Rajamanickam is kidnapped by Kayavarnam. Meanwhile, Arul informs Subha that he does not want to marry her without her consent. Arul asks Subha to inform Saravanan about her whereabouts so that Saravanan can come and rescue her. Subha informs Saravanan and he arrives at the place but gets shocked to see Arul’s henchmen there. It is revealed that it was a plan by Kayavarnam and Arul to kill Saravanan. Vetrivel also arrives there and he beats everyone and saves Saravanan and also saves Rajamanickam. Finally, Subha is married to Saravanan.
