Leader

<p>Sakthivel is a widower living with his daughter Irene in <a title="Thoothukudi" href="https://en.wikipedia.org/wiki/Thoothukudi">Thoothukudi</a>, working as a car mechanic under his landlord Thangapazham. His employer’s biggest client is Salt Raju, a powerful smuggler controlling illegal operations at the harbour under international don Yuvaraj.</p> <p>Indhra, an honest police officer, is investigating these illegal activities but lacks support due to corruption within the department. After an undercover agent she planted is killed, she approaches Sakthivel for help in wiring a car for surveillance, but he refuses.</p> <p>Soon after, Sakthivel receives a threatening call claiming his daughter has been kidnapped and placed inside a container at the harbour. He storms the location, only to discover the container holds ammonium nitrate, not his daughter. Indhra reveals this was a ploy to expose the smuggling network and that Irene is safe.</p> <p>As pressure mounts, Indhra’s superior Bakthavachalam takes control of the case and hides the key evidence. Meanwhile, Salt Raju retaliates against Sakthivel by targeting those close to him and coercing him to retrieve the seized container. Sakthivel complies but secretly plants a bomb inside it. A corrupt official falsely clears the contents as fertilizer, allowing Salt to reclaim it—only for the container to explode, destroying the illegal materials.</p> <p>Following the incident, Bakthavachalam is suspended due to media pressure. Indhra then discovers that Sakthivel is actually Ponmaran, a former covert operative, who has been orchestrating these events with the help of her father Sathyamoorthy. Under threat from Bakthavachalam, Sathyamoorthy reveals Ponmaran’s past.</p> <p>Ponmaran was once the leader of a 12-member Indian covert ops team. During an operation, he partnered with Meera, and the two fell in love and had a daughter, Irene. While tracking a rogue intelligence officer, their team became the target of a mysterious assassin known as “Devil,” who began eliminating members one by one. Unable to identify the killer, Ponmaran disbanded the team.</p> <p>Later, the team was unofficially reassembled to rescue Indian students held hostage in a foreign nation. During the mission, suspicion fell on Meera due to her recent inclusion in the team. In reality, the “Devil” was Yuvaraj, who was the twin brother of their contact Robert, seeking revenge for his father’s death. He manipulated events to frame Meera, forcing Ponmaran—under orders—to shoot her, while the remaining team members were killed by the Devil.</p> <p>Ponmaran was imprisoned for six years for his actions in helping the students escape. Upon release, he discovered Irene had grown up in an orphanage and believed him responsible for her mother’s death. Choosing not to reveal the truth, he assumed the identity of Sakthivel. With Sathyamoorthy’s help, he began dismantling Salt Raju’s network, which had been threatening the orphanage.</p> <p>In the present, Yuvaraj arrives in India to eliminate Ponmaran. However, Ponmaran collaborates with Bakthavachalam and Indhra to expose the entire criminal network. The harbour is cleared of explosives, and Yuvaraj is eventually captured.</p> <p>While trying to escape by train, Ponmaran is shocked to see Yuvaraj, who reveals a final twist—that they are triplets name is Martin and the person captures earlier was his brother. A final confrontation ensues, where Ponmaran defeats him. Before killing Yuvaraj, Ponmaran reveals that Meera survived the gunshots due to <a title="Dextrocardia" href="https://en.wikipedia.org/wiki/Dextrocardia">dextrocardia</a> and is alive.</p> <p>In the end, Ponmaran reunites with both Meera and his daughter Irene, bringing closure to his long ordeal.</p>
