Amarnath, leader of DYP, tightens his hold over Nanchenkotta through threats and torture. He runs illegal gun manufacturing and uses goons to terrorize residents, driving many to abandon the land. The police are unable to act, leaving the town under his ominous shadow.

Adv. Lakshmanan campaigns to challenge DYP in the upcoming election, urging people to vote against Amarnath. His rally is cut short when Amarnath's henchman Ummar kills him, crushing any hope of a fair electoral fight. The killing underscores the extent of Amarnath's influence over the region.

With Lakshmanan's death and mounting pressure, Vyshakan, the in-charge of Nanchenkotta police, commits suicide after his daughter criticizes him for his inability to act. The event marks a blow to the town's already fragile law and order. It signals a deeper collapse of trust in formal institutions.

A new leader of the rival party begins making unilateral decisions to win voters, creating discontent among older members. Sooraj, a senior party member, and several others resign to work for the people instead of the party. This shift signals a grassroots push countering Amarnath's grip.

The rival leader hires a goon to take out Amarnath, hoping to tilt the balance. The attempt backfires when Amarnath's mastermind kills the hired gun, preserving his own reign. The failed hit further inflames the town's sense of danger.

SI K arrives in Nanchenkotta and burns a goon alive who had seized the police station. He rallies the other officers and begins clearing Amarnath's goons, often using methods that skirt the law but restore order. This marks a turning point as the authorities openly resist Amarnath.

K confronts Appu at the illegal gun site and demands it be shut down. Ummar arrives at the police station to threaten K, but K stands his ground and refuses to work under Amarnath. The standoff heightens tensions between the regime's enforcers and the reformist officer.

Under Amarnath's orders, Ummar attempts to force K to leave Nanchenkotta or be eliminated, but K resists. Ummar, along with his men, assaults two policemen, severing one of the officer's legs in the attack. The assault hardens K's resolve to challenge the gang.

K relentlessly tracks Ummar to a factory where he and his allies regroup. He engages in combat with Ummar and defeats him, ultimately severing Ummar's legs with a chainsaw. The brutal triumph signals the erosion of Amarnath's inner circle.

Sooraj meets with K and asks for help to win back the trust of Nanchenkotta's residents. K begins working for the people against DYP, triggering Amarnath's wrath. In retaliation, Amarnath's goons kill a policeman and stab K, but K endures and repels the assault.

Amarnath orders Sooraj's assassination, dealing a heavy blow to the town's morale. The loss shakes the locals and undermines confidence in the political process. K's resolve to confront Amarnath grows stronger in response.

K abducts Appu, brutalizing him and leaving him in a coma to break Amarnath's grip. Amarnath is forced to kill Appu to end his suffering and swears vengeance on K. The violence escalates toward a final confrontation.

Sangeetha refuses to become the next candidate and departs Nanchenkotta for Hyderabad after a cop threatens her. Her withdrawal removes a potential counterweight to DYP's dominance. The move underscores the high price paid by reformers under Amarnath's regime.

In the climactic fight, K defeats Amarnath and drags his body through the streets, ordering that no one move until prison authorities arrive. The town's people who had fled return to walk over the unconscious dictator, signaling a fragile peace. K then leaves Nanchenkotta to restore order elsewhere in Tamil Nadu.
