Several murders have taken place throughout
Kolkata, for which a
serial killer is believed to be responsible. The killer strikes in accordance with verses of
Bengali poetry, which he leaves next to his victims. The police are baffled;
ACP Abhijit Pakrashi struggles to solve the case, which takes a toll on his relationship with his girlfriend, Amrita Mukherjee, a
TV journalist. Abhijit's superior officer,
Commissioner Amit Kumar Srivastav, brings back ex-
DCP Probir Roy Chowdhury, to help solve the case. Probir, who was suspended for his violent methods, is notoriously ill-tempered and foul-mouthed. Probir and Abhijit work together, while Amrita and her colleague Surjo Sinha, research serial killers for a TV series, whose thirteenth-and-final episode will be about a contemporary killer. Meanwhile, eccentric poet, Nibaron Chakraborty, who considers himself to be a part of the
Hungry Generation, wanders Kolkata at night reciting poems. For her research, Amrita visits a prison where the warden remembers Rafique Ahmed and his only confidant during his 18 years of imprisonment: Nibaron Chakraborty. She and Surjo go to Nibaron's house to question him; after being greeted by his servant, Swapan, they are convinced he is insane when Nibaron says he has a meeting with "Rabindranath". They almost succeed in learning about Rafique when Surjo angers him by mentioning the book fair arson, for which he was imprisoned. While investigating the case, Abhijit sees Amrita and Surjo together. Jealous and drunk, Abhijit goes to Probir's house and pours out his heart; he tells Probir that he lost his father at a young age, and tries to avoid alcohol because of what it did to his father. Probir tells Abhijit that he went to work the day after losing his wife and child, encouraging him to be strong. Surjo takes Amrita to a cemetery, telling her that he would propose to her in a few days. However, a police constable sees them and mistakes the couple of trying to have sex. Both Surjo and Amrita end up at the police station after she slaps the police officer. Abhijit, still tipsy, rescues them when the officer recognises Amrita as his girlfriend; the duo reconcile. The next day, while randomly discussing poets and poems, Probir and Abhijit deduce that the killer strikes on the death anniversaries of well-known Bengali poets. When they search all possible days the killer could strike, they discover that the next date is 29 June, which is the death anniversary of
Michael Madhusudan Dutt. Amrita tells Abhijit what she and Surjo have been doing, including the interview with Nibaron. This convinces him that Nibaron is the killer, especially when Swapan tells Probir about his employer's nightly walks around the city. The duo visit Nibaron as journalists and try to understand his stance on the Hungry Generation. It becomes clear that Nibaron does not consider the movement to be a failure, and has no regret about his attempted arson at the book fair years ago. Abhijit and Probir watch Nibaron's house on the fateful night. A hooded figure comes out; it is Swapan, who tries to flee. He reveals that Nibaron has been very depressed, and has been burning all his poetry. Going back to his house, they find that Nibaron has committed suicide, discovering another couplet beside his body. They both realize that this was the final murder. The case is closed, and Probir is congratulated by the police department for solving the case. After a month or so,
Rabindranath Tagore's death anniversary (
Baishe Srabon) arrives. Probir invites Abhijit to meet a man named Rabindranath Mitra, a publisher. Abhijit is shocked to find that the man he knew as Swapan is actually Probir's servant, Kanai. Probir admits that he was the mastermind behind the murders, with Kanai, an ex-convict, carrying them out as per his orders. He was vengeful of the police force for his suspension, which he considered an insult to his hard work, despite the loss of his family. It was easy for him to frame Nibaron, since his case was handled by Probir years ago. The latter had told Rabindranath to meet Nibaron regularly regarding publishing his poems, and when he suddenly refused, it led to Nibaron committing suicide. He also says that Nibaron's death was not the final murder. Abhijit believes himself to be the next victim. However, Probir makes it very clear that he considers himself a murderer, and intends to kill himself since he "hates murderers". After reciting the last couplet, Probir shoots himself in the head while a pleading Abhijit watches in horror. ==Cast==
