SP Arjun Sarkaar is imprisoned for an unspecified crime. In jail, he is saved by a fellow prisoner named Samuel Joseph from being harmed by inmates he had previously arrested. Later Arjun narrates his story to Joseph through a series of flashbacks. Following the events of HIT: The Second Case, Arjun is posted to HIT Vishakapatnam in place of Krishnadev "KD". He murders a civilian by hanging him upside down in a forest and slitting his jugular vein. He further records the act. Afterwards, he is assigned to investigate his own crime, further revealing organs were removed from the corpse after the murder. Meanwhile, he begins a romantic relationship with Mridula, a woman he met through a matrimonial site set up by his father. His colleague, ASP Varsha IPS, grows suspicious of him and starts tracking him, witnessing Arjun commit another murder in the same manner. Confronted by her, Arjun justifies his actions revealing the two civilians killed by him were pedophiles and undeserving to live. A flashback reveals that when Arjun was posted to HIT Jammu and Kashmir, he investigated a similar murder and apprehended the killer after a fierce fight with his accomplices, only to later discover a similar murder having been committed in Bihar, where the culprit was apprehended. On inquiring him, Arjun discovered that both killers were members of a dark web cult organization called CTK (Capture, Torture, Kill), which required members to record two such murders to join. Following the suicide of the first killer in custody and the death of two of his accomplices who were Azad Kashmir activists, Arjun was transferred to HIT Visakhapatnam.[b] Having decided to infiltrate CTK, he committed the murders, uploaded the videos, and gained membership. Tracking a CTK killer to Jaipur, Arjun prevents another murder and apprehends the killer but is stabbed. As he recovers, CTK’s leader, Alpha, welcomes him into the organization.
