Sethupathi I.P.S

From a family devoted to public service, Sethupathi carries a strong sense of duty. His mother Satyabhama is an IAS officer, his maternal grandfather is a decorated soldier, and his father-in-law serves as an Inspector General of Police.

In a hospital, Sethupathi corners the terrorist Sivasubramaniam and compels him to reveal crucial details. The confrontation establishes the leverage needed to disrupt the planned attack.

Sivasubramaniam discloses that the gang intends to strike the Prime Minister during a meeting with Chief Ministers in Chennai. Sethupathi uses the moment to extract actionable intelligence for a timely takedown.

After revealing the plot, the terrorist takes his own life using Sethupathi's firearm. The death ends the interrogation but leaves the authorities with critical information to act on.

Using the intel, Sethupathi coordinates with security forces to prevent the strike during the Prime Minister's visit. His timely action averts a national crisis and saves countless lives.

Sivaprakasam—brother of the fallen terrorist and the gang's new leader—lands in India and begins to consolidate control. His arrival signals a dangerous escalation for Sethupathi and the country.

Pretending to be a kind man named Satyaprakasham, he wins over Sethupathi's mother, wife, sister, and grandfather. The family accepts him into their circle, setting the stage for further manipulation.

Sivaprakasam engineers an engagement with Saraswathi, Sethupathi's mute daughter, gaining the family’s trust. The fake romance paves the way for the future wedding and the gang's influence.

Following the engagement, the gang hijacks a school and demands a plane and money to flee abroad. The hostage situation begins, placing Sethupathi at a critical nexus of personal and national stakes.

Sivaprakasam brings his wife, Sethupathi's sister, to the site and the attackers let the assault unfold. Sethupathi's wife witnesses the horror and shoots the sister; Sivaprakasam responds by shooting a boy student, escalating the tragedy.

Sethupathi arrives at the school and, after secretly killing one terrorist, infiltrates the attackers in disguise. He eliminates Sivaprakasam and the remaining men and ensures the plane can land safely under the injured pilot's guidance.

With the crisis resolved, Sethupathi is awarded his grandfather's medal in a public recognition of his service and sacrifice. The moment caps off his personal and professional triumph.
