One of the best films from Balaji Sakthivel and Vikram. Set up in 2000s the movie showcases the corruption in the country, where Thiagu along with his team try to bring up something for the society, Nassar portrays the character as Santhanapandian, ACP.
The film starts with Thiyagarajan (Vikram), a student in medical school, going to visit his childhood friend, Nisha. On the way, he meets a kind-hearted but naughty schoolgirl, Deiva (Anita Hassanandani). Deiva, who stays with her grandmother, is the daughter of police officer Sandana Pandian (Nassar). Sandana has a run-in with Thiyagu but later realizes that Thiyagu is actually a good person.
Thiyagu meets up with his four friends to kidnap a politician for his dirty doings at which time he finds out that Sandana and Sandana's wife (Bindu Panicker) are neighbors and good friends with his friend. After the dirty politician gets kidnapped, Sandana is appointed to investigate the case. Meanwhile, Thiyagu undergoes training to make his body and mind fit like that of his friends. Thiyagu then kidnaps another five people also for their dirty doings. Sandana is unable to catch the culprit.
During this time, Nisha's friends try to molest Deiva. Unable to bear the trauma she experienced on her own, she returns to her parents. However, Sandana is already stressed out from the investigation and doesn't want to hear about Deiva's problems. Thiyagu helps to relieve Deiva's anxiety by telling her she now knows how to avoid that type of situation in the future. After that, Deiva, not knowing his true identity, falls in love with Thiyagu.
A flashback shows Thiyagu's studious classmate, Kavitha, (Jaya Seal) writing in her diary about things she wants to tell Thiyagu but never does. Although Thiyagu gets irritated with her, he still loves her. While attending medical school, Kavitha discovers that a pharmaceutical company distributed dangerous medicines that caused a boy's death. When she tries to expose the company, no one, not even Thiyagu or her friends, supports her because they don't know the boy.
This upset her so much she commits suicide. Before dying though, Kavitha asked Thiyagu to get revenge for the boy's death on her behalf. After much thought, and after reading Kavitha's diary, Thiyagu and his friends decide to take revenge on those who use a loophole in the law to complete their prison sentence in guest houses and hospitals. Sandana discovers that the next target is a minister who is behind the pharma crime for which Kavitha committed suicide. Even though Sandana tries to protect him, the minister still gets kidnapped.
Later Sandana finds out that Thiyagu is the man responsible for the kidnappings. Knowing Pandian is behind him, Thiyagu tries to escape. When Deiva conveys her love to Thiyagu, he reveals his identity to her. Pandian captures Thiyagu and puts him on trial in an open court with many magistrates and other people. They ask him to release the people he kidnapped but Thiyagu argues that he will only release them after they are punished with a death sentence. The magistrates deny the request stating there is no law that has such a punishment.
The abductees end up being released, and everyone that heard Thiyagu's argument form a protest and kill all the abductees. Sandana takes Thiyagu and his friends away in a van but releases them saying that Thiyagu is right, there is a need for such a law that gives the culprits a punishment of death. As Thiyagu is leaving, Deiva shows up which reminds him of how he felt about Kavitha. Deiva tells him that Kavitha is always with him just as she will be and the film ends with Thiyagu and his friends leaving with Deiva.
