On a cold winter morning in Lutyens’ Delhi, the room service staff at Nagaland Sadan discover a decapitated head. The victim Jonathan Thom, a Naga leader, was in Delhi for the important Naga Business Summit. IPS officer Ansari leads the murder investigation. Meanwhile, Hathi Ram, investigates a migrant worker's disappearance, only to chance upon a startling discovery.

DCP Bhardwaj reviews CCTV footage of Raghu Paswan and Rose Lizo. Hathi Ram hopes to join Ansari on the case but is turned down. Hathi Ram investigates a lead that leads to a drug bust but ACP Virk claims the credit. A video of three masked individuals claiming responsibility for Thom's murder stirs media frenzy. In Nagaland, a constable spots Rose Lizo.

Hathi Ram and Ansari meet SP Meghna Barua in Nagaland who is sceptical of their presence. Tensions rise at Thom's funeral at the arrival of Thom's estranged son Reuben. Hathi Ram and Ansari learn of Thom’s illicit businesses. A drug dealer, a potential lead in their case, ends up dead. And so do the three individuals who had claimed responsibility for Jonathan Thom’s murder.

Hathi Ram and Ansari investigate the murder of the three individuals, only to realise that the three were set up for this. Hathi Ram discovers Raghu Paswan’s link to Reddy’s hotel before travelling to Delhi for his son’s birthday. Meanwhile, Ansari discovers a lead on Rose Lizo and goes looking for her, but so do Reuben and Daniel, Thom’s security officer.

The police look for Rose Lizo in the jungles she last disappeared in. Daniel is out there looking for her too. Hathi Ram deals with a personal tragedy in Delhi, and an enquiry into what went wrong back in Kohima. Unable to live with the fact that Ansari is being made the scapegoat, Hathi Ram decides to take matters in his own hands.

Hathi Ram and Meghna unite their meagre forces against a raging mob of Thom’s supporters that attacks the hospital Rose Lizo is admitted in. Hathi Ram investigates the murder of a businessman and realises that Reuben has been made the fall guy for the murder. A personal injury leads Hathi Ram to the startling discovery that Rose has a child.

Hathi Ram is abducted and taken to meet Reuben but Meghna manages to be on the tail. Hathi Ram finally comes face to face with Reuben and discovers Reddy’s close links with Thom’s drug business. ACP Virk helps Hathi Ram discover Daniel’s connection to Langchoma which helps Hathi Ram make a startling discovery about Uncle Ken. But before he can reveal it to Meghna, a tragedy strikes.

Hathi Ram confronts Daniel on Christmas eve and finally manages to avenge Ansari’s death. The business summit is a success in Delhi and Uncle Ken is hailed, forcing Hathi Ram to reconsider his choices. Hathi Ram returns to Delhi and eventually manages to learn about Raghu Paswan’s innocence and his unnecessary death.
