Sakthi is studying Engineering in a college in Chennai, and he gets into quarrels every other day. Not able to withstand the threats from hooligans, his billionaire parents-mother and father pack him up to his mother's village in Pollachi where his maternal grandfather Velayutham and grandmother Sivagami are from. Though the grandparents are rich and respected farmers cultivating paddy, Sakthi has not met them due to a small dispute between his dad and grandfather. In that village, an innocent third cousin of Shakthi, Kaipulla, lives with the old couple with hopes of becoming their heir, but kaipulla is comical and useless for farming. He has a small club and roams around the village with his mates. Kaipulla is constantly challenged by Sakthi's distant relative body-builder Kattadurai, who is also a rich landlord. Sakthi visits his grandparents and decides to stay there for a month. A marriage of their relative is planned, and the whole family from all over Tamil Nadu assembles. Neelaveni, who accompanies her relatives, falls in love with Sakthi. Kattadurai is supposed to marry Neelaveni.

Many events follow. Kattadurai often clashes with Sakthi and gets beaten up. Amidst the wedding preparation, a group of former enemies including Vaira Kannan and Neelavani's aunt, along with Neelaveni's father, kidnap Neelaveni. Sakthi goes after them. After a huge tussle, Sakthi brings back Neelaveni. Whether they unite or not is the rest of the story.
