A worker at a mining site in Dhegohaat Forest makes a unique find because of which Rueben Bhatta wants that government-protected land, but it belongs to a tribe that hates outsiders.
Bhatta trusts Dr Sanghamitra Das to lure the Dhegohaatis. Pullappa, a broker for contract killings, searches for Sarju as Special Crimes officer Aditya Dutt is after his men.
Pullappa saves Sarju from the authorities. Sanghamitra gains the trust of the tribe, who in turn spurn Rueben's offer of a good life. The medical camp leaves them scarred for life.
Dutt awaits information on Pullappa. After Sarju's father's death in the massacre, Sanghamitra gets him to the city to look for the masterminds behind the bloodbath.
Pullappa misleads Sarju and uses him to get his job done. As Sanghamitra reveals Bhatta's plan to the media, Dutt is assigned the medical camp massacre case.
Sarju rescues Kisna from Dutt's clutches. Pullappa comes up with an almost impossible plan to kill Bhatta in Georgia and Setu Lam is brought into existence.
