Sivagiri alias Giri, a bladesmith in a remote village near Thirupaachi, has a lovable sister Karpagam and runs into hilarious incidents while searching for a groom for his sister. When a city guy proposes to Karpagam, Giri accepts their relationship. Giri accompanies the newlyweds to Chennai. On a trip to Chennai, Giri rescues a court witness from Pattasu Balu, a gangster dominating Central Chennai. Giri also learns about Pan Parag Ravi, a local gangster dominating North Chennai and also responsible for troubling Karpagam's husband's canteen business.
During an altercation at a theatre, Kannappan gets murdered by Saniyan Sagadai, a gangster dominating South Chennai. Karpagam's husband tells Giri to leave Chennai for his sister to be happy. After Kannapan's funeral, Giri leaves his hometown and says that he received a job at a cloth manufacturing company in Erode. However, Giri is still in Chennai with intentions to finish all gangsters. Giri calls Sagadai and states that he will kill him. Giri also calls ACP Raj Guru and says that he will eradicate the city's gangsters. Inspector Veluchamy, Giri's friend, initially refuses Giri's methods, but later helps Giri in the mission after his son Arun gets killed by Balu.
Veluchamy provides a list of the city's entire crime network to Giri by providing the specifications of leading gangsters in various areas. Giri writes their names and soon kills Balu. Later, Giri provokes Ravi to kill his brother and Ravi hides in a politician's house to escape from Giri. Ravi damages the politician's house and vehicles to make the police believe that someone has attacked his house. The police decide to provide security for the politician. Through Veluchamy, Giri learns that Ravi is hiding in the politician's house. He brings a group of people, who rally due to losing their money to a fraudulent financier hiding in the politician's place.
With the rally, Giri enters Ravi's fort and kills him. Raj inquires about the people involved in the rally regarding the identity of Giri, but nobody wants to inform anything because they think Giri is doing the right thing. Raj's daughter does not reveal Giri's identity as Giri rescued her from Balu earlier. Later, Giri sets out to kill Sagadai and warns him. Sagadai seeks the protection of a mass group of thugs from the city. Giri uses this as an opportunity to destroy the city's crime network. Giri ignites a war between the police and gangsters in a very diplomatic manner. Giri disguises himself as a cop and enters Sagadai's fort. Veluchamy helps Giri in his mission by injuring himself and Raj orders his squad to hit the thugs.
Giri confronts a thug and forces him to wear a police uniform, where he kills the thug and throws him out of the window. Thinking that one of his fellow officers is dead, Raj and the cops kill all the thugs, but they discover Giri's plan and run upstairs to find him. Giri stabs Sagadai and throws him to the ground right before the New Year, thus avenging Kannappan's death. In the aftermath, Giri reunites with his girlfriend Subha, Karpagam, and her husband.
