The police discover a stranger in a cell closed for 50 years. The life of Jailer Mostak Ahmed, under various pressures from his family and superiors, becomes more miserable.

The jail authority secretly brings in a sign language interpreter to communicate with the stranger. The stranger claims that he has been in prison for 250 years.

The inmates begin to address the stranger as 'Gazi Peer'. Gazi Baba pronounces people guilty or innocent just by looking at their eyes. Meanwhile, it is revealed that Gazi Baba has come from a secret prison in Andaman.

Gazi Baba's prolonged interrogation enrages his followers. Deputy Jailer asks Mostak, what if the widely known story about this cell happens again?

Mostak Ahmed and Gazi Baba face each other. Unable to control his temper, Mostak raised his hands on him.

Raju, a prisoner who got caught thanks to the powers of Gazi Baba, is extremely angry with him. On the other hand, Mostak and the Deputy Jailer count hours till night when they will finally find answers to their questions.
