One day a rotten skeleton of a human hand is found in the drains of the slum but SI Ram Charan dismisses it by calling it an animal's hand and providing some money to the boy who discovered the hand. Later Prem kidnaps the boy, and chops his body into pieces after killing him. He has a friend Chote Lal with whom he runs a business of organ trafficking and both of them share the money they get from the business.
In a flashback, a child Prem is seen abused by his uncle(who is a butcher), who raped him daily but one day Prem attacks him, chopping him into pieces.

SI Ram Charan registers FIR of Chumki's disappearance and reaches Balbir, who brushes off Chumki's father saying he is the pimp of her daughter to which Ram Charan beats Chumki's father and asks him to get out. Ram Charan's senior officer warns him to not involve Balbir Bassi in anyway into the case. He finds Chumki's mobile phone with the auto-driver, who had dropped her at Balbir's residence. He comes to know that Prem had given the mobile to auto-driver to throw it off but auto-driver didn't and that Prem is directly involved in this case leading to his temporary suspension for not following the orders of his senior.
After getting back to duty, Ram Charan takes Chote Lal into custody and he confesses that Prem had made Chumki disappear. His senior officer Rastogi now under pressure that Ram is near to the truth, bribes off Ram's junior officer Shravan Kumar Pathak to hand over Chote Lal to assassins and when Ram Charan finds that Chote Lal is missing he thrashes Pathak as to his carelessness resulted in the disappearance of an important witness but is calmed down by his senior officer and with the testimony provided by auto-driver, Ram arrests Prem Singh and interrogates him and to his shock, Prem reveals everything as to how he kidnaps kids, rapes them, chops them off after killing them, eats some of the meat, throws some and does organ trafficking and earns money(which he sends to his family), regarding to Chumki, he admits raping her after killing her(because she refused his advances) and chopping her after that, leaving Ram Charan and his senior in shock but when asked about Bassi's involvement in all of these he denies to answer. Ram Charan beats him off and asks why he did all of these to which he answers that the kids he kidnaps are of no use to the society and their lives doesn't matter.
