Srijit Mukherji's Cop Universe

Srijit Mukherji's Cop Universe is an Indian media franchise and shared universe created by Srijit Mukherji, consisting of media focusing on police officers who predominantly solve cases of serial killers. The universe was established by crossing over common plot elements, settings, cast, and characters.

The first film, Baishe Srabon (2011) focuses on Probir Roy Chowdhury, an ex-DCP who is returned in his duty when incidents of serial killing begin in Kolkata. He is assisted by ACP Abhijit Pakrashi. The second film, Vinci Da (2019) focuses on DCDD Bijoy Poddar, who arrests corrupt people who were being accused falsely by Adi Bose, a 'serial lawyer', with the help of Vinci Da, a makeup artist. The third film, Dwitiyo Purush (2020), a spinoff sequel to Baishe Srabon, focuses on the life of (now DCDD) Abhijit Pakrashi, eight years after the events of the prequel, when he tries to solve a new case of serial killing that involves a former gangster Khoka. Pakrashi is assisted by a young police officer Rajat Chakraborty. The fourth film, Dawshom Awbotaar (2023), a prequel to all the previous films, brings together Probir Roy Chowdhury and Bijoy Poddar in solving a case of serial killing that involves a connection to the ten avatars of Lord Vishnu.

Baishe Srabon (2011)
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.

Abhijit is having a torrid time with his wife, Amrita, as he suspects her of having an affair with her journalist colleague, Surjo Sinha, and decides to start his investigation with a younger fellow officer, Rajat Chakraborty, much to the despair of Amrita, who was looking forward to mending their relationship.
