Back-up dancer Sandhya is murdered under mysterious circumstances, casting a shadow over Indrajith and his pop-band. The police suspect Indrajith, but there is no evidence tying him directly to the crime. The case sets the tone for a high-stakes investigation around his life.

Sandhya's sister Divya arrives at her aunt Dr. Prabhavathy's house to learn what happened and clear her sister's name. She immediately clashes with Indrajith and starts gathering perspectives from his circle. Her visit marks the start of a personal investigation that intersects with the ongoing police case.

Divya questions Indrajith's manager Harichandra Prasad and other musicians, hearing mixed opinions about Sandhya. The conversations reveal tensions, secrets, and possible motives, but no solid evidence linking anyone to the murder. The rumors push Divya further into the mystery.

In a bold move to provoke a reaction, Divya stages an attack in a bar, forcing Indrajith to step in to protect her. He saves her and takes her to his concert, bridging their initial hostility with a fragile trust. The incident sets off a chain of events that intertwines Divya's fate with the killer's attentions.

During the concert, Jennifer, a devoted fan, climbs on stage and kisses Indrajith. That night, Jennifer is killed by someone wearing Indrajith's coat, deepening the police's suspicions against him. The event sharpens the thriller's pace and stakes.

With no conclusive evidence, the police tighten their scrutiny on Indrajith, and Divya is warned that he may be involved in Sandhya's death. The pressure forces Divya to consider Indrajith's potential guilt and fuels their complicated dynamic. The investigation expands beyond one murder to a possible serial pattern.

Divya stages a kidnapping to test Indrajith's knife skills, exploiting the fact that all previous victims were killed with precise cuts. The ruse lays bare the killer's methods and adds a tense layer to their cat-and-mouse dynamic. Indrajith reluctantly plays along, unsure of who to trust.

The next day, Indrajith sees Divya walking out of the hospital with a bandaged kidnapper, realizing she was faking her affection. This revelation shifts the balance of trust between them and propels the duo toward the truth. The scene heightens emotional stakes in the pursuit of Sandhya's killer.

Indrajith opens up to Divya about Sandhya: she was unstable and abusing substances, and had threatened suicide if he didn't reciprocate. He had tried to help her and had believed that was the end of their connection. This confession reframes Divya's perspective on Sandhya and deepens their bond.

The killer uses incriminating photos to blackmail Indrajith, forcing him to appear at murder scenes minutes after the murders. The tension escalates as Indrajith becomes entangled in a dangerous game that he must navigate to clear his name. The mystery widens while the killer carefully orchestrates every move.

During a long cat-and-mouse chase, the killer is revealed to be Harichandra Prasad, Indrajith's manager. He attacks Dr. Prabhavathy but she survives the confrontation. The discovery reframes the mystery and exposes professional jealousy as the motive.

Indrajith discovers similar clothing in Harichandra's closet and uncovers a secret room filled with photos of the victims. The chilling find confirms a serial pattern and ties Harichandra to the murders. The evidence strengthens the case against him.

The killer kidnaps Divya and instructs Indrajith to come to an abandoned house with the photographs. This perilous lure amps up the final act, bringing the couple to a confrontational climax. The abandoned setting adds to the film's eerie mood.

In a giant chase and fight sequence, the killer is killed and Indrajith's name is cleared. The threat ends as Divya and Indrajith reconcile, and everyone else moves forward after the killer's defeat. The story closes with a sense of resolution and happiness.
