Plot: The story is set in the backdrop of Madurai where a gang is involved in kidnapping top businessmen in the city and demand a sum of Rs. 2 crores for their release and failing to do so will result in their death. The dead bodies are placed beneath a bridge. Bhavani (Bangalore Swamy) and Lal (Murali Tiwari) are the main culprits behind the kidnaps and Albert (Harish Uthaman), a police inspector cracks the case and unearths the criminals involved in kidnap, but gets killed by Bhavani.

Jayaseelan (Vishal) is the new ACP who gets deputed in his hometown Madurai. Murugesan (Soori) is the head constable and is a close friend of Jayaseelan. Jayaseelan wants to have a meeting with Bhavani and his gang to finalize his commission so that he will never interfere in their illegal activities. But actually, Jayaseelan is in undercover operation to encounter Bhavani and his gang.

Jayaseelan lives in a joint family with his parents and elder brother Selvaraj aka Selvam (Samuthirakani). Meanwhile, Jayaseelan meets Sowmya (Kajal Aggarwal) and falls in love with her. Jayaseelan encounters two of Bhavani’s men. Now Bhavani is frightened knowing that someone has set an eye on him and he will be the next target. Jayaseelan tracks down Bhavani also and kills him. Just before dying, Bhavani challenges Jayaseelan that kidnapping incidents will continue after his death which leaves Jayaseelan puzzled. It is Jayaseelan’s elder brother Selvam who is actually the masterbrain behind all the kidnaps. He is the close friend of Lal, who is an advocate and both are involved in planning the kidnap while Bhavani is involved only to execute the plan.

A small flashback is shown about Jayaseelan’s family. Jayaseelan’s grandfather Ramasamy is a freedom fighter and is widely respected by the local people. He also served as a minister and is known for his genuineness and loyalty. But his son, who is Jayaseelan’s father, is not interested in politics and he prefers to stay away from politics following his father’s death. Meanwhile, Singarasu (RK), a local politician decides to bank on Ramasamy’s political support for his victory.

Singarasu convinces Selvam to support his party for which Selvam agrees. Singarasu wins the election and becomes MLA. Selvam is encouraged by a few party men to contest for MLA seat during the next election. But Singarasu is the man behind the plan and he wants to defeat Selvam to show his power. Selvam trusts a few friends but later understands that it was Singarasu's plan. Selvam loses the election as Singarasu provided money to vote for him to the public. This made Selvam furious and he decides to earn more money and use it for election purposes. He makes his close friend Lal to earn the confidence of Singarasu and collects all the information about his illegal business activities. Also Selvam and Lal are involved in kidnapping rich businessmen in the city demanding money.

Coming to the present, Selvam knows that Jayaseelan is handling the kidnap case and closely monitors his moves. Lakshmi Narayanan (Jayaprakash), father of Sowmya is kidnapped by Selvam and his men demanding money. Lakshmi Narayanan hands over the money to Selvam who appears with a mask in front of him while collecting the money. Next day, a meeting is arranged between Jayaseelan and Sowmya’s family members to discuss their marriage proposal. At that time, Lakshmi Narayanan observes the mannerisms of Selvam and doubts that he could be the one who kidnapped him the day before. Selvam also understands that Lakshmi Narayanan has got a doubt on him and decides to kill him before he could contact Jayaseelan. Lakshmi Narayanan requests Jayaseelan to meet him immediately but Lakshmi Narayanan is killed by Selvam before that.

Jayaseelan formulates a plan to find the culprit. He decides to tap the mobile phones of all the leading businessmen in Madurai, so that he can get to know if the kidnapper calls any of them demanding money. A special team is set up who are involved in phone tapping. A businessman gets a call demanding money and Jayaseelan decides the follow the person without anyone’s knowledge. While the businessman is about to hand over the money to Selvam and Lal, Jayaseelan interferes. Selvam and Lal escape from the spot and is chased by Jayaseelan. Lal is shot by Jayaseelan and gets arrested. But Selvam shoots himself in hand and stages a scene that someone has shot him and ran away.

Jayaseelan believes the show staged by Selvam and admits him in the hospital. Meanwhile, Lal is killed by a hitman employed by Selvam. Selvam’s father overhears his conversation and understands that Selvam is the man behind all crimes. But Selvam decides to kill his own father also. In the meantime, Jayaseelan conducts a secret investigation against his brother Selvam and finds the truth. He has got enough evidence that Selvam shot himself based on the number of gun shots heard and also understands that his brother staged a show that he was shot by the culprit who ran away. Jayaseelan goes to Selvam’s place and finds a secret room behind where his father is tied to a chair. Jayaseelan saves his father and brings back home.

Now Selvam is shocked to know that all his illegal activities are exposed to his family members. He requests them not to take any action as he will become the next minister post election. Suddenly Selvam rushes to kill Jayaseelan and his father. Jayaseelan retaliates and hits Selvam. Finally their father asks Jayaseelan to kill Selvam saying that it will be a big embarrassment for their family especially their grandfather Ramasamy’s image in the society if the truth comes out to public. Jayaseelan agrees and kills his brother Selvam and puts the dead body beneath the bridge where usually the kidnappers place the dead bodies of rich businessmen staging a scene that Selvam is also killed by the kidnappers demanding money. In the meantime, Jayaseelan encounters Selvam’s hitmen involved in crimes with him as the culprits behind the kidnaps and closes the case.
