In the rain-drenched, melancholic landscape of Kolkata, the city is gripped by terror as a series of gruesome murders targeting the intellectual elite begins. Each crime scene is meticulously staged, accompanied by lines of haunting Bengali poetry left behind by the perpetrator. The police force is baffled, leading to the desperate reinstatement of Prabir Roy Chowdhury, a suspended, foul-mouthed, and fiercely intelligent former detective known for his unorthodox and often brutal methods. Prabir is a man haunted by his own broken past, driven by a cynical worldview and a relentless obsession with justice that transcends legal boundaries.To assist in
the investigation, the department assigns Surya Sinha, a young, idealistic, and by-the-book
crime reporter whose calm demeanor acts as a stark foil to Prabir’s volatile aggression. As the two men navigate the city’s dark underbelly, their professional friction evolves into a complex psychological chess match. Prabir believes the killer is a disgruntled poet seeking validation through blood, while Surya struggles to reconcile his moral compass with the gruesome reality of the crimes. The narrative delves deep into the themes of existentialism, the power of literature, and the thin line separating the hunter from the hunted.As the investigation intensifies, the tension culminates in a shocking revelation: the killer is not an external villain but someone deeply embedded within the social fabric of the city’s literary circles. The perpetrator is revealed to be a man whose life was shattered by the same systemic indifference that Prabir fights against. The climax is a harrowing confrontation that forces Prabir to confront his own demons and the futility of his violent crusade. In a tragic twist of fate, the killer’s final act of poetry is written in the blood of those he deemed unworthy, leaving the audience to question the nature of sanity and the true definition of a crime. The film concludes with the haunting realization that while the killer is caught, the scars left on the city and the detectives remain permanent, forever tethered to the rhythmic, sorrowful verses of Baishe Srabon.
