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 (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 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 misunderstand his 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 with false pretences, with disastrous consequences.

Shiva, who's an unwilling witness to her distress, is shocked at his brother's callousness. Thus begins a cat-and-mouse game between the siblings that escalates with every step.
