Murugavel works as a police constable in Virudhunagar and lives for his younger brother Ravi. He makes repeated attempts to steer Ravi away from antisocial behavior, but Ravi's actions escalate. Eventually Ravi runs away from home in search of a so-called better life.

Murugavel is posted as a sub-inspector in Chennai, stepping into a larger, tougher environment. He quickly discovers that Ravi is entangled in snatching and other crimes. Ravi is working for Meesa Padma, a local gangster who exploits underage youths for his schemes.

Ravi continues his criminal activities in Chennai and becomes entangled with Meesa Padma, a local gangster who uses underage workers. Murugavel starts connecting the dots, realizing Ravi's involvement while Padma's operations loom large. The rift between brothers deepens as Ravi's loyalty to Padma grows.

Ravi plots to kill Murugavel by adding poison to the food bought for him, but Murugavel refuses to eat for three consecutive days, foiling the attempt. This act heightens the peril around Murugavel and forces him to rely on caution and vigil. The family tension shifts into a larger criminal confrontation.

At the market near his vegetable shop, Murugavel encounters Madonna, a policewoman who visits shopkeepers to collect bribes. The meeting hints at budding collaboration and a potential romantic thread. This encounter also places Madonna at the center of Murugavel's city-side battles against crime.

One night, Ravi plans the next snatching operation near Murugavel's shop, only to learn that his target is actually a police officer. This revelation escalates the danger as Ravi realizes his brother is on the opposite side of the law. The confrontation sets up a direct personal clash between the brothers.

Murugavel chases Ravi through the streets and ultimately kills him in a police encounter. The act marks a brutal turning point, ending Ravi's criminal trajectory and establishing Murugavel's reputation for decisive action. The city begins to see him as a dangerous, capable officer.

Following Ravi's death, Murugavel is promoted to Inspector, recognized for his bold leadership. However, the promotion coincides with ongoing battles against high blood pressure and insomnia rooted in stress and past traumas. He resolves to continue serving the city despite his health challenges.

With his new rank, Murugavel commits to solving city problems and taking down Meesa Padma's gang. Madonna supports his mission, and their professional relationship deepens into a personal bond. The struggle shifts from personal family conflicts to a broader city-wide crime fight.

Two young boys working for Meesa Padma slit Murugavel, gravely injuring him. Madonna intervenes, foresaking fear to save him and rushes him to the hospital. The attack strengthens the alliance between Murugavel and Madonna as they prepare for the climactic showdown.

The young boys realize their mistake and switch sides to aid Murugavel. In the climactic confrontation, Murugavel faces Meesa Padma and defeats him, dismantling Padma's criminal network. The city begins to breathe easier as Padma's influence wanes.

Murugavel is promoted to ACP and finally feels a sense of peace after a vision of Ravi apologizing for his mistakes. The former insomnia eases, and his blood pressure stabilizes as he sleeps soundly. The city wakes to a stronger, more hopeful police leadership.
