Vetrivel (Vijay) is a race car driver who lives with his large family in Chennai. His father, Singamuthu (Manivannan) had gone to Kadapa in Andhra Pradesh for work at a colliery and never returned, prompting Vetrivel and his family to think he is dead. Vetrivel comes to know that a gentleman named Koccha (Suman) owes his father a huge sum of money. Finding that Koccha is based in Malaysia, Vetrivel and his friend Pons (Vivek) fly to Malaysia, as Kuruvi, the trade jargon for low-level contraband carriers. He steps into the group at a time when internal rivalry and problems are surfacing in Koccha's family. Koccha's darling sister Devi (Trisha Krishnan) has refused to marry the former's business associate Konda Reddy's (Ashish Vidyarthi) brother, the boy approved by her family members. Irritated and preoccupied, nobody wants to devote any time or attention to resolve Vetrivel's problem. Vetrivel is abused, harassed, suffers more ill-treatment and is thrown out of Koccha's place without any help rendered. These callous actions enrage the young man. Totally enraged, with a do-or-die attitude, deciding to get his work done no matter who gets hurt, Vetri becomes a veritable suicide machine and launches into a terrific scuffle with the dangerous gang. Determined to return only after the issue is solved to his satisfaction, motivated by an urge to reveal the truth, Vetrivel conceals himself in Koccha's palace-like residence. He returns to India after stealing a large diamond that was in Koccha's possession.
