Detective

Rashmi is found dead under mysterious circumstances at her home, and the initial ruling labels it a suicide. The death plunges her family into grief, with her father Prabhakaran Thampi blaming Mohan Kumar. Investigators begin to question the official cause as doubt spreads.

The family grieves deeply while Prabhakaran directly accuses Mohan of being responsible. The party suspends Mohan as a parliamentary candidate and installs his ally Jose as the new MP. Public reaction grows tense as the political stakes rise.

Jose maintains Mohan's innocence and stands by him. SP James Joseph campaigns to persuade others that Mohan could be innocent, fueling public doubt about Mohan's involvement. The political atmosphere tightens as allegations swirl.

A suicide note emerges claiming that Mohan was the cause of Rashmi's death, triggering deeper scrutiny of the case. The note casts doubt on Rashmi's decision to end her life and prompts investigators to look for hidden motives. The case shifts from a suicide to a possible murder.

Shyam Prasad, Mohan's step-brother and a renowned detective, is appointed to lead the investigation. He is joined by a team including Basheer, Shekhar, Rajeev and Aravind. The ensemble begins a methodical, high-stakes inquiry.

Shyam and his team visit Rashmi's house to question relatives and collect early clues. Rashmi's father is cautious, reiterating his belief that Mohan is connected while withholding direct accusations. The house becomes a focal point for initial leads.

Suresh, a relative, provides context about Rashmi and Mohan's engagement and why her family opposed it. The explanation shifts attention to Rashmi's relationships and the dynamics surrounding her marriage. The investigation widens beyond surface allegations.

Shyam's investigators uncover that the suicide note was fabricated by James and John Samuel. This revelation confirms Rashmi's death was a murder, not a suicide, and strengthens the case against the conspirators. The team compiles fingerprints and other proofs to seal the truth.

James and John Samuel attempt to eliminate Shyam by sending goons after him. Shyam resists the attack, and the would-be killers are arrested. The confrontation demonstrates that the higher-level conspirators are being targeted.

In a conference with the DGP and Chief Minister, Shyam presents the facts showing Rashmi was murdered. He reveals that Rashmi had been pretending to love Mohan to escape the trouble, and that Sumesh is the killer. The revelation shocks the room and shifts public perception.

Sumesh is confronted by Shyam and questioned; after pressure he admits his role in Rashmi's murder and explains his motive. The team documents the confession and the mechanics of the crime to build the final case against him. Evidence is collected to support the confession.

A flashback reveals Sumesh and Rashmi were childhood sweethearts who drifted apart as she pursued Mohan. Rashmi had wanted to marry Mohan, while Sumesh sought revenge when her family opposed the match. He devised a poison milk plan, using a ventilator pipe and a thread to deliver the poison and staged a suicide to hide the murder.

Sumesh is arrested and the DGP and Chief Minister praise Shyam for solving the case. Rashmi's family apologizes to Mohan for doubting him, and Mohan shares a relieved smile with Shyam as the investigation ends. The team leaves the conference hall with the truth finally in the open.
