Omana Omana’s body is discovered on the grounds behind her house, appearing to be a suicide by leaping from the roof onto the rough stone pavement below. The case is assigned to an upright, honest police officer, SP Prabhakara Varma, who is aided by Circle Inspector Alex. The investigators begin by questioning Omana’s close circle: her husband Sunny, her father-in-law Ouseppachan, a local businessman, Narayanan, along with the household staff and neighbors. Sunny admits there was a quarrel with Omana the night before and that he pushed her onto the bed before stepping out to drink, though he maintains he did not strike her and notes that Omana had reportedly attempted suicide in the past. Ouseppachan provides a different version, saying he returned home from a business trip, was locked out, and only found Omana’s body after going around to the cook’s quarters. The inconsistencies in these testimonies begin to mount, casting doubt on the official suicide ruling.
The Regional Medical Officer confirms death by head trauma at 8:00 P.M., but Omana’s cousin, Chacko, a constable, spots suspicious details. He notices Ouseppachan praising a servant for something questionable and challenges the autopsy report, suggesting the timeline and blood evidence don’t quite fit. He informs the investigation team that it rained heavily until 9:30 P.M., so if Omana had died at 8:00 P.M., her body would have been wet and the blood would have mixed with rainwater. The bribery-laden atmosphere around the case becomes clearer when Alex warns Ouseppachan to steer Varma and Chacko away from the case. Realizing Varma’s potential to disrupt the cover-up, Ouseppachan enlists Narayanan to pull strings with politicians to have Varma shifted away, while also moving Chacko out of the way.
A new investigator, DYSP Devadas, arrives, and he uses intimidation to push a quick, clean conclusion: Omana died by suicide. He also pressures Omana’s grieving family and witnesses to keep quiet, effectively stalling the truth. The case then threads its way to the CBI when Omana’s father, Thomachan, and her sister, Annie, insist on pursuing justice and take the matter to the central bureau with the assistance of Chacko. The CBI Director assigns Sethurama Iyer, the Deputy Superintendent, to head the renewed inquiry, aided by CI Harry and SI Vikram. Iyer’s team digs into political interference and uncovers a troubling pattern: a surge of calls to Ministers and Party Leaders from Narayanan’s number and cash withdrawals from Ouseppachan that never show up in the books.
To probe further, Iyer and his teammates bring two dummies matching Omana’s height and weight to Ouseppachan’s residence. The test, which drops one dummy straight down and tosses the other as if thrown, shows Omana’s corpse would have landed in roughly the same area, indicating she could not have jumped from the roof on her own. They then track down Vasu, Ouseppachan’s driver who has been missing since Omana’s death. He reveals that he delivered jewelry as collateral for a loan; among it is a bracelet belonging to Omana. Vasu explains that Narayanan had visited him the night Omana died, telling him that Sunny had accidentally killed Omana during a domestic altercation and urging him to move the body and throw it from the roof. In the moment alone with Omana’s corpse, Vasu notices her bracelet and decides to steal it before carrying out the act.
Vasu’s testimony implicates Sunny, yet Iyer remains unconvinced. If Sunny left the house at 8:00 P.M. after striking Omana, the blood evidence and the scene don’t align with that timing. A closer look at the crime-scene photographs reveals a small bloodstain on Omana’s saree below the waist, a detail the autopsy had missed. Blood typing confirms the sample is O-negative, a rare blood type in town. A broad blood-dlood screening, prompted by a recent malaria-driven mandatory testing, shows that only three people in the town carry O-negative blood.
Armed with this new clue, Iyer returns with a substantial police presence and arrests Ouseppachan for Omana’s murder. The revelation hits Sunny hard, and guilt-stricken, he confesses that he accidentally killed Omana by hitting her too hard during their quarrel. Iyer explains that Omana did not die from the blow; she had fainted, and the crucial blood on her saree did not belong to her. The discovery narrows the killer’s circle to those with O-negative blood, and the investigation finally converges on Johny, Ouseppachan’s son-in-law. Johny admits he came to the house the night Omana died, found her unconscious on the bed, and, after attempting to rape her, suffocated her when she woke and screamed. In the process, he wounds himself and leaves his own blood on the saree.
Confronted with the mounting evidence, Johny owns up to the murder. The case closes with a sweeping sense of justice, driven by meticulous forensics, careful testimony, and the unyielding pursuit of truth by Sethurama Iyer and his team. The narrative moves from initial, muddled testimonies through political pressure to a forensic-backed resolution that lays bare the lethal consequences of ambition, deceit, and the darker currents within the community.

Sunny admits an argument the previous night and says he did not hit Omana, while Ouseppachan provides a different account of arriving home and discovering her body.
When:8:00 PM Where:Omana's house grounds

Autopsy results and timing raise suspicions
The Regional Medical Officer rules Omana's death as head trauma with the time of death around 8:00 PM. The finding feels inconsistent with a clean suicide given the circumstances, prompting investigators to probe for possible foul play. The case begins to shift from a simple accident to a potential homicide.
When:8:00 PM Where:Local hospital autopsy room

Chacko suspects inconsistencies and notes rainfall
Omana's cousin Constable Chacko points out inconsistencies in testimonies and the autopsy report.

He informs Varma of the rainfall timing, prompting deeper scrutiny of the case.
When:late evening Where:Police station and vicinity

Corruption and rapid dismissal of the initial investigation
Alex is taking bribes from Ouseppachan, and Narayanan uses political influence to push for Varma's removal. Chacko is also sidelined from the case as a new, bribed DYSP Devadas takes over. Devadas quickly concludes the inquiry by declaring Omana's death a suicide, sidelining earlier doubts.

Rooftop theory tested with dummies
To test the suicide theory, Iyer's team brings two dummies matching Omana's height and weight to Ouseppachan's house.

Blood evidence narrows the suspect pool to O-negative carriers
