It was theatrically released on 23 January 2020, as a tribute to detective writers, Agatha Christie and Arthur Conan Doyle.

In October 2023, Dawshom Awbotaar, a prequel crossover of Baishe Srabon and Vinci Da was released, thus making Dwitiyo Purush the third installment of Srijit Mukherji's Cop Universe.

In 2019, DCDD Abhijit Pakrashi, who is regularly haunted and traumatized by Probir Roy Chowdhury's suicide, is assigned a case by the Commissioner Dibakar Bose, to capture Khoka, who was released from prison a month ago and already committed the murder of his rival gang leader, Haroo, in exactly the same fashion and place from 1993.

Abhijit, with the help of Surjo, retrieves the archived news footages and finds that a person named Gora, was allegedly present in all the previous murder scenes.

Meanwhile Abhijit and Amrita reconciled earlier after marriage counseling, but their happiness was tinged with the high number of tragedies, which followed one after another.

Abhijit, disoriented, gains control of his rage, captures Jimmy, and forces him to call Khoka at the old, burnt down mill in ChinaTown, for the final showdown.

Initially, Abhijit disagrees with the whole story, but finally breakdowns implying that he accepts the fact that he is the real Khoka.
