A slick entertainer, the story begins with the happy go lucky Vetrivel (Vijay) and his best pal Ops (Vivek) who take life as it comes. However, Vetrivel is in for a surprise when he is asked to vacate the house they are staying and on further enquiry, he gets to know that his father (Manivannan) has been running into debts and has given a cheque that has bounced. Assuming that his father must have gone undercover due to the financial mess, Vetrivel and Ops go to Malaysia to locate the person who has signed the cheque and discover that it is none other than Koccha (Suman) the dreaded don who along with his counterpart Konda Reddy (Ashish Vidyarthi) have imprisoned his father in the quarry mines of Cuddapah in Andhra Pradesh since he has not agreed to their unlawful means of quarrying. Vetrivel becomes Kuruvi, a jargon used for petty contraband carriers and enters the kingdom of Kochcha. Meanwhile, there is Devi (Trisha), sister of Kochcha who is unhappy about the marriage decision taken by her elders and a twist of events take place which make Vetri and Devi fall for each other. Vetrivel takes all the ill treatment by Kochcha and his henchmen only to get his father back but realizing that it is not happening, he comes back to India along with Ops and Devi. Kochcha comes to India in search of Vetri and then starts a fearless war by Vetri who will not stop at anything to bring the sinners to justice. What is the plan he has in mind? Is he successful in getting back his father? All this forms the rest of the story.
