Aadhavan

In the United States, an unknown client is shown speaking to a mafia group to eradicate a fake godman. The mafia group arranges the hit through a middleman who is in Kolkata, as the fake godman will be arriving there. The middleman then gives the contract to Ibrahim Rowther. The godman is then killed by an unknown man, who is revealed to be Ibrahim's adopted son, Aadhavan. Aadhavan is a skilled mercenary working with Ibrahim and adopted older brother Tharani. Aadhavan then gets several contracts in various parts of the world as a result of eradicating the godman. As a result, the trio gets richer. In Mumbai, Aadhavan meets Dr. Abdul Kulkarni, who hires him to kill a prominent justice, Subramaniam, since he is handling the inquiry and verdict on Abdul's child kidnapping and organ trafficking cases in Kolkata. Aadhavan attempts to snipe Subramaniam, but fails at the first attempt seemingly. After that, Kulkarni insults him for his failure to kill Subramaniam. Aadhavan then becomes furious and vows to kill Subramaniam within 10 days. He threatens Subramaniam's servant Kuppan aka Bannerjee to help him get into the house as Murugan, Bannerjee's brother in law, by abducting the actual Murugan and have him held in his ship.

Slowly, Aadhavan begins to win over the members of Subramaniam's household – his mother, her beautiful granddaughter Thara, and his other relatives. Thara is attracted to Murugan's (Aadhavan) intelligence and simple-innocent nature. Aadhavan tries to assassinate Subramaniam at home in the middle of the night and also plants a bomb in Subramaniam's van, but both attempts fail. Meanwhile, Subramaniam's entire family is on a trip to Darjeeling, and Thara asks Aadhavan to hide a guitar belonging to Ilaiyaman, her madcap musician cousin whose name is a portmanteau of Ilaiyaraaja and A. R. Rahman. Aadhavan uses this opportunity, plants a mobile bomb in the guitar, and places it in one of the cars, which explodes at the wrong time, thereby failing to kill Subramaniam yet again. Meanwhile, a security officer, who is the chief of the security team protecting Subramaniam at Subramaniam's house, keeps informing Kulkarni of Aadhavan's entry into the house and all his signs of progress and failed attempts. Thara is now suspicious about Aadhavan, but when she questions him in secret, he informs her that he is really Subramaniam's long lost runaway son Madhavan. Thara soon informs all the members of the household about Madhavan's return, and they are overjoyed, with Thara and Aadhavan falling in love.

However, they hide it from Subramaniam and Ilaiyaman because of the former's hatred towards Madhavan. Aadhavan, however, tells Bannerjee that he lied to Thara about being Madhavan to distract her suspicions and that he really is not him at all. However, on Thara's birthday, a flashback reveals that Aadhavan is indeed the runaway Madhavan. Years ago, a 10-year-old Madhavan unknowingly carries a gift with a hidden bomb for his cousin Thara's birthday. His friend's mother plants the bomb in the toy as revenge against Subramaniam for her gangster husband's jail sentence. Though Thara survives, her mother Anu opens the box and is killed along with her husband in the explosion. Subramaniam blames Madhavan for his sister Anu's death and for his friendship with a gangster's son and thrashes him. In anger and fear of going to a juvenile prison, Madhavan steals a gun from the cops, accidentally shoots Subramaniam, and runs away from home. He kills his friend's mother as she is responsible for his aunt Anu's death. He saves Ibrahim, then a local goon from death, and is in turn adopted as his son and as 'Aadhavan'.

Tharani tried to kill Subramaniam but is stopped by Madhavan and reveals his true identity that he is Subramaniam's son. Ibrahim challenges that he will kill them within two days. Kulkarni is fed up with the repeated failed attempts of Madhavan. He makes another plan, threatens Ibrahim and his gang to surrender to the police, and makes a confession about Madhavan and his plans. When the ACP confronts Madhavan and is about to have him hauled off, Madhavan gets Subramaniam's laptop containing the verdict and inquiry reports, takes him and Thara as hostages, and drives away, but not before stealing the ACP's gun and using to injure him and the guards, when they intervene on him, but even killing the security chief. Meanwhile, the police commissioner arrives, arrests the ACP, as the latter is revealed to be another informer for Kulkarni, and makes a confession that the police actually had caught Madhavan after his very first attempt to kill Subramaniam had failed. When questioned by the commissioner, Madhavan said that he backed off and misfired on purpose at the last moment after he found that he was going to kill his own father, Subramaniam. The police then ask him to go back to the house to protect Subramaniam over a 24/7 hiatus time every day, for which he agrees.

The commissioner uses Madhavan to nab individuals linked to various criminal and terrorist organizations. This information is relayed to Subramaniam by the commissioner, who is tearfully grateful to his son, Madhavan. Meanwhile, Kulkarni attacks the vehicle in which the trio is travelling, and a fight ensues where Madhavan saves Subramaniam and Thara and Kulkarni is killed. The minister and the middleman that was involved in the contract killings get arrested. Madhavan serves a short term in prison for his previous wrongdoings but is subsequently released from the prison for his contribution to saving Subramaniam. Madhavan and Thara are now married, live in the household with the huge family. Once yet again, Bannerjee brings two assistants (his brothers-in-law) to help him and asks approval from Subramaniam, who then consulted in Madhavan, to check them out, with the whole family being suspicious of them being secretly hitmen. Upon inquiring on them, he approves of them with the whole family accepting them.
