An unknown young man keeps showing up in Alamgir's nightmares. Alamgir's daughter, Srabonti, starts searching for the young man with suspended DBI officer, Ehsan.

Imprisoned for five years, Sumon refuses to help Srabonti and Ehsan. Parvin says Sumon was never associated with Samad Party. Sumon's case is reopened but in secret.

During the investigation, Srabonti and Ehsan find out that there is no Samad Party member named Sumon. Meanwhile, there has been no trace of the Samad party leader in the past five years.

Tamal and his wife try to hide something. On the other hand, Parvin tells Srabonti that Sumon was with her all day on the day of the incident. Meanwhile, Ehsan finds Samad.

After getting caught by Ehsan, Samad confesses that he made Tamal unconscious on the bus and that the 23 lakhs were in his bag. How did a simple composer of the land office manage to get his hands on so much money?

Dipti had died in a road accident shortly after winning a bitter legal. Ehsan and Srabonti chase real estate businessman Rana.
