Aaru

Aaru is raised by Vishwanathan's sister and grows to regard him as a brother. He is determined to keep Vishwanathan as a powerful influence in Chennai. This loyalty shapes his every move as the feud unfolds.

Vishwanathan declares war on rival Kothanda Rama Reddy and mobilizes his forces. Aaru supports him and pushes deeper into the conflict. When Reddy's goons strike, Aaru overpowers them and proves his loyalty in battle.

The protest is organized to consolidate power, and Aaru attends. He leaves the protest midway to propose to his girlfriend Mahalakshmi. She declines and tests his loyalty by giving him two months to change and stay away.

During the protest, Aaru's friends are burnt alive after kerosene is mixed with gasoline. The tragedy fills him with regret, fueling his vow to exact vengeance. He resolves to confront those responsible.

Lingam reveals that Bhaskar started the fire, raising suspicions about Vishwanathan. Vishwanathan blames Reddy, yet the two have already colluded to finish Aaru and expand control over Chennai. The fragile trust between Aaru and his allies begins to crack.

Aaru confronts Reddy, who lays bare the truth and exposes Vishwanathan's true nature. Reddy's revelations set Aaru on a mission to destroy the corrupt power behind the attacks. The confrontation intensifies the feud.

Betrayed, Aaru slices Reddy's neck and vows to destroy Vishwanathan's power. He declares that he will go to any lengths to bring down the man who betrayed him. The act cements Aaru's path of vengeance.

Aaru kidnaps Vishwanathan's third younger brother Jaganathan and slices his hand to send a stark message. He challenges Vishwanathan to save his loved ones, making clear that his reach has limits. Rajavelu, a corrupt cop and Vishwanathan's brother-in-law, obtains a shooting order to eliminate Aaru.

Aaru plans a bold strike during a property registration, wearing masks with his men. They break into the registrar's office and disable Bhoominathan, ending his ability to stand against them. The operation demonstrates Aaru's willingness to escalate violence.

Rajavelu fires a bullet into Aaru's shoulder, and he escapes before reinforcements arrive. Maha's friend nurses him back at her home, and Maha finally acknowledges Aaru's love for her. The couple's bond deepens amid the ongoing conflict.

Aaru's calls to Vishwanathan about Bhoominathan's fate provoke a ruthless reply: Vishwanathan unplugges the life-support machine and Bhoominathan dies. Vishwanathan annihilates many of Aaru's allies, tightening his hold on the city. Rajavelu arrests Maha, while a female officer harasses her at the station, pushing Aaru to act.

Aaru breaks into the police station to rescue Maha, thwarting Rajavelu's plan to break her spirit. He safely retrieves her and carries her to safety. The scene marks Aaru’s resolve to protect his partner at any cost.

Vishwanathan's second younger brother Loganathan and Bhaskar pursue to finish Aaru. Aaru sends Maha to Sri Lanka for safety. The brothers clash; Bhaskar dies as fire consumes the scene, and Loganathan dies in the blaze after a fatal turn of events.

Rajavelu pretends to arrest Aaru with other officers, hoping to lure Vishwanathan into the trap. Aaru wakes, defeats Rajavelu, and ties him to a tree. Vishwanathan arrives and the two clash, culminating in Aaru severing Vishwanathan's arms and exposing his vulnerability.

Aaru serves his prison term and is released. He reunites with Mahalakshmi and they depart for Pune to start a new life together. The saga ends with a sense of new beginnings despite the cost of vengeance.
