The film has a deceptively casual beginning: a middle-class family consisting of parents (Kuyili and Ponvannan), a daughter and twin sons—Shiva (Jiiva), who works in a fish-market and Ashok Kumar (Jiiva, again), who is a lawyer. Shiva is a typical hero who attacks baddies with his bare fists; a rugged man who’ll brook no injustice. Devout Ashok’s goodness is a facade that hides his evil womanizing nature. Both have romantic interests; Shweta (Divya Spandana) is Shiva’s long-time sweetheart. Ashok’s life is one long, lustful journey as he charms every woman he meets into his bed. This is where the tale picks up. Shiva can do nothing right as far as his parents are concerned; they trust the Ashok and always misunderstand Shiva’s righteous anger and his every attempt to show up his Machiavellian twin fails. Ashok, on the other hand, is pally with the local goons and uses his brains to assist them in their nefarious activities. Matters come to a head when Ashok lures a girl called Gayatri (Honey Rose) with false pretences, ends up in having sex with her and eventually causing her to suicide when he learns that she becomes pregnant. Shiva lodges a complaint on Ashok but this fails as he couldn’t prove that whether it was him or Ashok who did the crime due to their faces. Shiva comes to know that a security man who saw Ashok pushing Gayatri from the roof. He tells the security man to meet him in the evening. But he is killed by Ashok as the security man saw him in the evening and thought him as Shiva. Shiva comes to know this thus begins a cat-and-mouse game between the siblings.

During the fight the younger brother get killed by his own man. The elder brother walks with his father who for the first time accepts him.
