While Afnan Chowdhury gets bail, Detective Branch gets hold of OC Harun. A dirty secret from Harun's past term at the Shakaripur police station threatens to rear its ugly head.

The cat gets out of the bag as the DB officers question Harun about an old bombing incident at a government rally and his hush-hush investigation.

It's a roll of the dice as Afnan desperately tries to get hold of Zara, and OC Harun tries to get away from the DB officers.

As flashbacks of the aftermath of the bombing incident keep haunting Harun, he begins to sink into the quicksand. Masum waits to face dire consequences.

Harun and Afnan are like two peas in a pod when it comes to their wits. While the DB officers are desperate to find a loophole in Harun's judgment in Masum's case, Afnan eagerly tries to know Harun's next move.

Old sins cast long shadows. As Afnan stumbles upon a close confidant of Harun by design, the common motive of Harun and Afnan start coming to the fore.

Harun plays his trump card and eradicates Afnan's master plan. In the meantime, the DB officers get closer to the reality of what happened with Masum after he went missing from custody.

Harun recalls his last face-off with Masum. He gets baffled to see someone who has known it all since their Shakaripur days.

Harun hits the bull's eye by playing his ace move to outsmart the DB officers. However, the arrival of a new player in the capital puts Harun in mortal peril.
