Allu Ramendran

Police driver Ramendran's jeep keeps getting punctured by nails, a misfortune that earns him the nickname Allu Ramendran. The nails seem targeted and affect only him, baffling colleagues and family alike. The recurring punctures set the tone for the strange ordeal he faces.

While inspecting a puncture, Ramendran nearly catches the culprit but misses him in the crowd. In the chase, he discovers a wallet with a childhood photo, suggesting a link to his past, but he cannot identify the man.

The repeated mishaps force Ramendran to take leave from the police. He uses the downtime to reflect on who is behind the nails and how to stop them.

Swathi is in love with Jithu, a hopeful unemployed man awaiting a Dubai interview. Jithu is shocked to learn that Ramendran is Swathi's brother, a detail he didn't know before.

With Swathi's future in mind, the family starts looking for a suitable groom and asks Jithu to come home with a marriage proposal under an arranged-marriage setup.

During Swathi's family's visit, Ramendran finds old photos of Jithu and confronts him. Jithu finally confesses that he was the nail culprit.

On the day of Jithu's interview, Ramendran chases the runaway Amruthesh and ends up taking his bike, leaving it roadside when the pursuit ends in a fall. The mishap soils Ramendran's certificates, and Jithu begins planting spikes on Ramendran's vehicle to exact revenge.

Ramendran imposes petty challenges on Jithu to win Swathi's hand, including two self-goals in a local football match and begging on the street. Jithu endures the trials and keeps trying to prove himself.

Ramendran rejoins the police force and, on his first day transporting a gun to the court, is targeted by another spike. The old curse seems not yet broken.

Alarmed, he and a fellow officer spot a suspect and chase him, but the custodial gun is stolen from the jeep. Ramendran is suspended and suspects Jithu of being involved.

At a local event, Ramendran spots Amruthesh, who had relocated to Bangalore. He is attacked by goons while following him, but Jithu arrives to save Ramendran, and the stolen gun is found with Amruthesh.

Everything is settled and Jithu is married to Swathi. Ramendran and Jithu set aside their differences and become family.

In the closing moments, Ramendran chases a person suspected of keeping spikes for Swathi and Jithu's wedding vehicle, with Jithu following to potentially shield him from blame.
