A serial killer named Rudra, believed dead five years ago, resurfaces in Bengaluru with a new kidnapping that shatters the city’s peace. The case draws in the CBI and marks a high-stakes depending on the old strategy. Anjali Vikramadithyan IPS, who handled the earlier Rudra case, is re-appointed to lead the new effort.

In Chennai, Arjun struggles with a rocky relationship with Krithika after accusations of cheating. To salvage things, he travels with his distant friend Vinoth to Bengaluru to meet her. The trip heightens personal stakes just as a new threat surfaces in the city.

Rudra abducts Krithika and sends a ransom demand to her father, pulling Arjun deeper into the case. Rudra makes it look like Arjun is the kidnapper, triggering mistrust and a nationwide manhunt. Anjali intensifies the investigation as the case becomes highly publicized.

Following the kidnapping, Anjali is suspended from duty and her family is placed under house arrest. Inspector Narayan is assigned to take over the case, shifting the investigative dynamic. The mounting pressure drives the team to chase increasingly elusive clues.

As clues unfold, Arjun deduces that Rudra's true identity lies with former ACP Martin Roy. He confronts Martin and a brutal fight ensues, leaving Arjun injured. The realization designates Martin as the mastermind behind the current crisis.

Martin confesses that Rudra's original identity traces back to Anjali five years earlier, and that he went rogue after being suspended. He murdered his wife and staged three high-profile killings to imitate Rudra. The revelation reframes the case and forces everyone to reassess who truly controls the killer.

Meanwhile, Anjali uncovers that the man she is chasing, Martin Roy, is the real Rudra. The cat-and-mouse dynamic shifts as she realizes the killer's identity. The discovery escalates the personal stakes for Anjali.

Anjali reveals her long-hidden motive: she created Rudra to avenge Vikramadithyan's death after a car accident caused by four drug-addicted youths. Vikramadithyan died while Anjali survived and gave birth to her daughter Shalini. By finishing the four youths through Rudra, she intended to close the case and get justice on her own terms.

Feeling guilt and aided by Narayan, Arjun and Anjali team up to trap Martin. They coordinate a careful plan to corner the killer and bring him to justice. The alliance marks a critical pivot in the pursuit.

Arjun distracts Martin long enough for Anjali and Narayan to close in, and Narayan shoots Martin dead. The climactic confrontation ends the killer's spree and brings the truth to light. The team breathes a sigh of relief as justice seems within reach.

Arjun and Krithika reconcile, acknowledging the dangers they faced and the growth they have achieved. Anjali and Shalini witness the moment, strengthening the family bonds. The case moves toward closure as truth reshapes their understanding of justice.

Anjali and Shalini listen to Vikramadithyan's last words, a haunting reminder of the past price of vengeance. The moment provides emotional closure and a sense of lasting peace for the survivors. The investigation ends with a hard-won justice and the family beginning to heal.
