Aalavanthan wants his sons to marry the daughters of their aunts so that their family can reunite once and for all. A reluctant Saravanan helps his brothers and father attend a temple function in disguise to kidnap and marry their cousins, but they kidnap their aunts. They run away before getting caught. Saravanan agrees to the plan after finding out that Periya Ponnu's daughter is none other than Maya. Periya Ponnu believes the kidnapping was by Pasupathy (Pradeep Rawat), the MLA and ex-servant of Aalavanthan's family. Periya Ponnu decides to run against him in the next election. Pasupathy sends men to kill the aunts, but the brothers save them, disguised as police officers. Using this disguise, the trio gain access to their aunts' house. There, their uncles (Abhishek, Sriman, Gowtham Sundararajan) help facilitate the brothers' affection to their daughters. The trio succeeds in gaining the daughters' love. Pasupathy provokes Periya Ponnu by wagering that if he loses to her, he will work at her home as servant, but if she loses, her daughter Maya will marry his son (Rajeev Govinda Pillai). Using his knowledge of politics, Saravanan helps his aunt gain popularity. However, a few days before the elections, the aunts find out that Saravanan's father is their brother Aalavanthan, who they believe killed their father. Their hatred towards Aalavanthan results in them getting Saravanan and his brothers arrested. Aalavanthan is hurt by his sisters' harsh words at him, and is hospitalized after suffering a heart attack. As Saravanan and his brothers are stuck in jail, his aunt has lost her popularity, due to Pasupathy's manipulation. Saravanan calls Rajasekhar, who bails out the brothers, and inadvertently exposes Pasupathy's dirty tricks. Refusing to lose, Pasupathy tries to bribe people to vote for him, but Saravanan and Kumaran foil his plan, giving Periya Ponnu the edge. Pasupathy arrives at the home to kill the family and take Maya, but Maya already escaped to elope with Saravanan. Saravanan, though, insists they go back. A furious Pasupathy reveals that he was the one who killed Aalavanthan's father, not Aalavanthan.
