Aadhavan (Suriya) is a professional killer/hit-man who works for Ibrahim Rowther (Sayaji Shinde) who is also his father along with Tharani (Anand Babu)- who is his brother. He is contracted by Abdul Kulkarny (Rahul Dev) to kill prominent Judge Subramaniam (Murali)(who is presently working on child kidnapping and murder cases in the eastern Indian belt for sale of their organs to foreign countries) but fails to shoot him at the first attempt. He promises to get the judge, angry with himself for having missed such a thing and uses the Judge's innocent servant Bannerjee (Vadivelu) to get into the house as Murugan, Bannerjee's brother in law (He locks up Bannerjee's actual brother in law Murugan in a ship and threatens Bannerjee with his name all the time)Slowly Murugan/Aadhavan begins to win over the members of the Judge's household- the Judge's mother (B. Saroja Devi), his other relatives and finally his niece- Thara (Nayantara). He tries to assassinate the judge in the middle of the night and also by planting a bomb in the van by which the judge is travelling to Darjeeling- but both attempts fail. In Darjeeling, Aadhavan is handed over a guitar belonging to the madcap, wanna be musician, would be husband of Thara- Ilaiman (Ramesh Khanna) by Thara to hide away. He plants a mobile bomb in the guitar and places it in one of the cars which soon explodes.Thara is now suspicious but Murugan informs her in secret that he is in fact the Judge's runaway son Madhavan who ran away from home when he was only ten years old. Thara soon informs all the members of the household except the Judge that Murugan is Madhavan- although in private Muruguan tells Bannerjee that he was only joking and that he is not Madhavan.However on Thara's birthday- Aadhavan shows that he is indeed Madhavan- when in a flashback it is shown that- young Madhavan carried a gift for Thara where a bomb had been planted by Madhavan's friend's mother as an act of revenge (Madhavan's father had put her husband in jail). Though Thara survives, her mother (Anu Hassan) opens the box and is killed along with her husband in the bomb explosion. Madhavan runs away from home- after stealing a gun from the cops, accidentally shooting his father and killing his friend's mother who planted the bomb in the toy.Meanwhile- Abdul Kulkarny is fed up with the attempts of Aadhavan and Ibrahim Rowther and decides to play his cards in another way. He persuades Ibrahim and his gang to surrender to the police and
