Vijay and Anitha secretly nurture their love while family tensions simmer, meeting on the common terrace rather than in public. They pretend to hate each other in front of relatives, but their private moments reveal deeper feelings. Their bond sets the foundation for the coming conflict.

An angry Raghavan confronts the couple after catching them in the act of stealing glances and notes. He insists on a transfer to Madras to keep Anitha away from Vijay. He also finds love letters that Anitha supposedly wrote, which intriguingly reveal her Madras address.

Vijay deduces that Anitha's new address is in Madras from the letters and heads there to reunite with her. He stops at a restaurant in Madras to eat and gather himself. The journey marks a shift from family conflict to urban danger.

Ignoring warnings, Vijay goes to the upstairs restroom and stumbles onto an illegal porn film shoot being run from the restaurant. The exposure is soon noticed by the restaurant manager and the people behind the shoot. The confrontation exposes a web of corruption at the heart of the city.

A fight erupts during the confrontation and Naidu's son trips on a broken bottle and dies. Vijay is blamed for the death and is forced to go on the run to clear his name. The root of the problem begins to reveal Naidu's criminal network.

Raghavan is put in charge of capturing Vijay and publicly announces a reward for information leading to his arrest. The chase moves into the streets of Madras as the case intensifies. His decision to pursue Vijay ties the rest of the plot to law and order.

Vijay is briefly caught by constables Ekambaram and Karpooram but manages a daring escape. In the scuffle, Ekambaram accidentally kills the restaurant manager who has been pursuing Vijay, and the death is later blamed on Vijay. The episode deepens the frame-up around him.

Rani, an auto driver who once served at Vijay's house, arrives just in time to rescue him from danger. She takes him to her house where Maruthayi sees him again and is convinced of his innocence. The reunion brings momentary relief amid the looming threat.

Raghavan arrives and arrests Vijay, but at the police station he realizes the innocence of his son and decides to help expose Naidu. He shifts from pursuing a suspect to seeking the truth behind the restaurant's crimes. The alliance indicates a dramatic turn in the case.

Anitha is abducted by Naidu's men, escalating the danger to Vijay and his allies. Vijay must break free not only from the custody but also from Naidu's clutches to save her. The stakes rise as the villain's grip tightens.

Vijay stages a daring escape from police custody and races to reach Anitha before Naidu's men do further harm. He battles through threats, ultimately rescuing her from danger. The rescue marks a turning point toward the final confrontation.

Vijay confronts Naidu in a climactic showdown and is joined by Raghavan, who arrives and shoots Naidu dead. He apologizes to Vijay for past actions and finally accepts Vijay's relationship with Anitha. With the villain defeated, the lovers' bond is no longer threatened.
