Issac John is found dead inside the office restroom, with the door locked from the inside. The scene prompts the police to investigate, and an initial assessment points to an accidental head injury from a slip-and-fall. The discovery notes John’s COPD history as a potential complicating factor.

Police, led by ASP Sandeep, begin the formal investigation. The case is initially treated as an accidental death due to the perceived lack of forced entry and no obvious confrontation. However, Sandeep senses there are inconsistencies worth deeper scrutiny.

Sandeep's instincts push him to suspect murder despite the early conclusions. He notes the door’s inward lock and the absence of a plausible escape route for a fall, suggesting someone intended to trap John.

Gibson George is questioned about John's affairs. He reveals that according to John's will, the business would pass to his USA-based brother Evan after his death, which complicates the presumed motive.

During questioning, one employee is found carrying sleeping pills, raising concerns about drugging or coercion. Investigators explore whether substances were used to manipulate the victims or to silence them.

Further follow-up reveals most employees are patients of Dr. Kuriakose, a neuropsychiatrist-neurosurgeon known to Sandeep. This connection broadens the scope of possible manipulation or medical involvement.

Dr. Kuriakose discloses that Meera, his wife and one of John's employees, was treated for depression after a stillbirth, and mutagens are detected in her blood. Tests also show mutagens in two other employees who complained of headaches and insomnia.

Investigation reveals V-Pharma, co-founded by John, is developing an antidote for a Human Mutagen Virus (Red Virus) intended to create a demand for the antidote. The employees were allegedly given the antidote via snacks and water, and monitored through DNA data extracted by a punching machine.

Secret files from John's PC include a blueprint of the office punching machine, which investigators correlate with the ongoing medical-testing scheme. The evidence suggests a coordinated system used to monitor and test the employees.

Sandeep analyzes CCTV footage and reconstructs the method: the employees lured John to the restroom, staged a coffee spill, locked the door, and used carbon dioxide poisoning while an operating vacuum muffled cries.

Despite the murder plan, Sandeep decides the case as an accidental death, expressing his conscience that the perpetrators may get away due to wealth and connections. The formal charges against the employees are not pursued.

Gibson is revealed to be involved in the illegal activities of V-Pharma, and in the end he is shown as the new MD of V-Tech, occupying John’s cabin with the employees watching him with clear resentment and unease.
