Selva is a self-built man who owns a small travel agency in Chennai, and works hard to achieve something in life. He is all set to marry his lover Priya. The city is under the grip of dreaded loan shark brothers Maha and Kumar who would go to any extent to wield their clout in the city.

During a rainy night, Selva comes across a drunk Maha, and within minutes, Maha is killed in mysterious circumstances. The blame falls on Selva. Kumar and his men want to bump off Selva. A perplexed Selva runs for cover. He sets out to find the real killer.

Past: Maha had abducted Gayathri Ramakrishnan, the only daughter of a wealthy Delhi-based businessman and has been using her solely as his personal slave for 9 months, revolting on the thought that even the richest and most powerful men in the country can't touch her. One rainy night, Gayathri escapes captivity and comes across the intoxicated Maha sitting on the road. She uses the chance to exact vengeance and kills him. She discreetly places the murder weapon in Selva's car, and Selva is framed.

Present: Selva's two friends are taken captive and killed off brutally by Kumar. Selva's travel agency are also destroyed by Kumar's men, and Priya's family escapes the city to save themselves. With his entire life turned around by a crime he did not commit, Selva takes a new avatar as he decides to wage a bloody war with the gangsters where he kills Kumar and the 8 members of his gang. To dispose of the bodies, he uses a meat grinder overnight and feeds the flesh to the pigs.

Though Selva and Priya take care of Gayathri, she discovers that she is pregnant with Maha's child. At the same time, Selva and Priya learns of Gayathri's origins from the TV news. Unfortunately, Gayathri commits suicide.
