Nanchenkotta, a fictional place on the Kerala-Tamil Nadu border, is ruled by Amarnath, the leader of DYP, a political party. Amarnath threatens and tortures the people to keep them under control, which leads many residents to relocate to neighbouring places. Nenchenkotta is filled with goons under Amarnath's command and DYP is also involved in illegal businesses like gun production. The other known members of the party are Amarnath's brother Appu and their cousin Dr. Sangeetha. Another rival party headed by Adv. Lakshmanan participates in election, but to no avail because of Amarnath's influence. Adv. Lakshmanan gives a speech about going against DYP and asks for the vote of the local people, but Lakshmanan is killed by Amarnath's henchman Ummar.
Even though there is a police station, the law is in Amarnath's pocket and the cops are unable to take any action against him. SI Vyshakan, the in-charge of Nanchenkotta, commits suicide after his daughter criticises him for his inability to take action in Lakshmanan's case. The new leader of the rival party and his subordinates start taking their own decisions without thinking about the people. They conduct a meeting to select the candidate for the upcoming election against DYP's candidate Appu. The new decisions are not well received and Sooraj, a senior party member, and several members leave the party to work for the people on their own. The same day, the new leader hires a goon to finish Amarnath, but he ends up getting killed by Amarnath.
Meanwhile, an SI (simply referred as "K") arrives at Nanchenkotta and burns a goon alive as he had taken over the police station. K rallies the other cops and starts clearing Amarnath's goons using illegal methods. K visits the illegal gun manufacturing site headed by Appu and threatens him to shut it down. In response, Ummar arrives at the police station and threatens K, but K orders Ummar not to work under Amarnath. On Amarnath's direction, Ummar tries to make K leave the town or kill him, but to no avail. In a final attempt, Ummar attacks two policemen and one loses his leg in the process.
An agitated K tracks down Ummar in a factory and thrashes him and his allies, where he chops off Ummar's legs with a chainsaw. Sooraj meets K and requests his help to convince the people to return to Nanchenkotta. K starts working for the people against DYP, enraging Amarnath. Amarnath's goons kill a policeman and stabs K, but K manages to defeat them. In the next step, Amarnath finishes Sooraj, which impacts the confidence of the locals. K kidnaps Appu, thrashes him so severely that he falls into a coma. Amarnath is forced to kill Appu to end his suffering and swears to exact revenge against K.
Sangeetha refuses to become the next candidate and leaves for Hyderabad after a cop threatens her. Amarnath asks K to arrive for a final battle. In the subsequent fight, K defeats Amarnath and drags Amarnath's body through the streets, where he orders no one to move until the prison authorities arrive. The people, who had left arrive and walk over Amarnath's unconscious body, thus establishing peace in Nanchenkotta. K secretly leaves Nenchenkotta and arrives at an unknown place in Tamil Nadu to restore peace and order.
