Prabhakaran "Prabha", a daring and dashing cop, is suspended after he decides to rescue an informer instead of aborting that mission, going against the direct order of the Commissioner. However, he gets posted into the Internal Affairs of the Tamil Nadu Police Department, by the Commissioner. Along with a team of 4 other suspended police officers, he is posted at a restaurant that masquerades as their base of operations. They are to constantly monitor the policemen in the city, looking especially for the morally compromised cops.
Meanwhile, his elder brother, Karthi, and sister-in-law decide to adopt a child after years of trying to conceive one. They decide to adopt Nisha, after observing how close she is to their family, thanks to Janani, Prabha's love interest, who works at the same orphanage. However, on the day that Nisha is to be officially adopted into Prabha's family, she is kidnapped. While investigating, Prabha learns about the modus operandi of the kidnappers and manages to track down the kidnapper's Audi car to a warehouse, where he attacks the kidnapper, Aadhi, and saves Nisha.
Prabha admits Aadhi to the hospital and uses him as a bait to capture his mysterious leader. Upon deducing this, the leader manages to kill Aadhi, despite surveillance by Prabha and his team. As Prabha starts digging into the case, he learns that the kidnappings are connected to an attack at the Commissioner's office in 1993 by a gangster named Michael, who is actually Aadhi's father and also the mysterious leader. He finds that his father, Sathya Moorthy, a former SI and now an Alzheimer patient, had dealt with the case earlier.
It is revealed that in 1993, Michael actually was running a human trafficking racket by asking his henchmen to pretend as parents and adopt the children from the orphanage, where they hand over the children to Michael after 3 years, in exchange for money. However, a couple filed a complaint about Michael's illegal activities to Sathya Moorthy, who gathered evidence against him. When Sathya Moorthy reached the commissioner's office to provide the evidence, Michael attacked and burned the commissioner's office, where Sathya Moorthy was hit on the head in the process and lost his memory shortly after the incident. Michael was arrested on petty charges, while Sathya Moorthy was ultimately suspended and ostracized.
After having learned about Prabha's identity, Michael kidnaps 20 children randomly in broad daylight and tells the parents to provide money for their safe return at a public restaurant. While Prabha's team leader Deva and his team waits at the bar to nab them, Prabha finds out that one of the adopted children's parents are actually Michael's henchmen. He immediately calls his colleagues and asks them to protect Janani and the children at the orphanage. However, one of his colleagues, Perumal, is ultimately killed after taking down Michael's men. Prabha stays back at the parents's house where he defeats Michael's men and learns that Deva and his team are in trouble at the restaurant, where the parents are dropping off the ransom money.
At the restaurant, Prabha realizes that Deva, his colleague and friend from the police department, is Michael's son and the mole in the department. Prabha is shot and left for dead, but he survives by falling into the garbage chute. Nisha is kidnapped again, but Prabha and his colleagues analyse the place where Michael is taking the children and tracks down the bus, however, Nisha is not present. Sathya tracks down and chases a concrete truck, with Deva in it, containing Michael's next consignment of children to be trafficked. Ultimately, he manages to rescue them and kill Deva. Enraged, Michael arrives at Sathya Moorthy's house, along with Nisha, to kill them, but Sathya Moorthy manages to regain some of his memories and shoots Michael to death. The children are safely brought back to the orphanage.
