Kinkar Karmakar is the black sheep of his family. When he unexpectedly gets the opportunity to serve as a green volunteer of the Forest Department, he doesn't think twice before setting out for his posting at Kumirkhali, Sundarban!

Hafiz introduces Kinkar to the Panchayat heads, visibly disinterested in the Sundari Bahini initiative. Kinkar meets the feisty Parbati for the first time.

When Makhan discovers Kinkar and Parbati together at night, Kalyani leaves no stone unturned to try and push Kinkar to the point of no return. Parbati reveals to Kinkar the monstrous plan chalked up by Kalyani, Radharani and Makhan.

When Kinkar and Kalua visit Sukumar, the latter hands them incriminating evidence against the evil trio of Kumirkhali. Kalyani sends the police after Kinkar.

Kinkar joins hands with Parbati to expose the culprits. When Makhan identifies the person who recorded his conversation with Kalyani and Radharani, he does the unthinkable!
