A common man named Kumaran (Bobby Simha) kidnaps the Chief Minister of Tamil Nadu, Yogeeswaran (Prakash Raj), at a private old age home event in Chennai. The news goes viral, and everyone from the local to the central cabinet starts taking the issue personally. Home Minister Thillainayagam (Ilavarasu) appoints Santhanapandian (John Vijay), the Police Commissioner of Tirunelveli, to rescue Yogeeswaran. Santhanapandian questions Bala (Bala Saravanan), a minister's son who was discovered unconscious at the scene of the kidnapping. Bala tells that he and Kumaran had become friends when Kumaran had saved him from a group of thugs, but they are shocked to see that they both of them love the same girl - Priyadharshini (Nikki Galrani). Bala also reveals that Kumaran willingly allowed him to pursue his relationship with Priyadharshini in exchange for making arrangements for Yogeeswaran to attend the old age home event.

Meanwhile, as Santhanapandian and his deputy, ACP Arivazhagan (Bharath Reddy), strive to get clues about Kumaran, Kumaran explains to Yogeeswaran his motive for kidnapping him. Kumaran was an orphan, but due to the efforts of an honest politician named Kumaraswamy (Nassar), who had sponsored him, he got a good education and became a journalist with the News7 TV channel. When he went to Kumaraswamy's house to thank him for his contribution to his life, he found out that Kumaraswamy had gone missing for many days. On further investigation, he learned that Kumaraswamy had been buried alive by Thillainayagam and his sons Kishore (Shan) and Prathap. Thillainayagam had contested against Kumaraswamy in the last election and had defeated him by rigging the vote, which forced Kumaraswamy to file a case against him and demand a recount. When Kumaraswamy refused to withdraw the case against him, Thillainayagam and his sons buried him alive. Kumaran then filed a case against Thillainayagam and asked Kumaraswamy's intellectually disabled son, also named Kumaran (Karunakaran), who was unaware that his father had been killed, to give the statement to the police inspector. However, the police inspector was Thillainayagam's aide and informed him about Kumaran. Thillainayagam's sons then took Kumaran on a bus and pushed him out en route. He was then run over by a lorry and died.

In order to avenge the deaths of Kumaraswamy and his son, Kumaran hatched a plan with Priyadharshini and Bala to kidnap Yogeeswaran in order to expose Thillainayagam slowly through false media reports based on false replies by Bala while being interrogated by the police. In the process, Thillainayagam's sons are taken into questioning. After being tortured, they eventually give in and expose Thillainayagam as Kumaraswamy's murderer, even giving them the location in Thillainayagam's lawn where Kumaraswamy was buried. Thillainayagam is arrested, and Kumaran releases Yogeeswaran. Kumaran also escapes from his hideout and poses as a journalist, while Yogeeswaran says that he cannot identify the kidnapper. Even Santhanapandian gives up on pursuing the kidnapper as the latter had kidnapped Yogeeswaran with good intentions.
