Shakti, Vikram Prabhu opens with a high-stakes move: a moving train is breached by cutting a hole in its roof, and the impulsive thief pulls off the heist with cool precision. The authorities waste no time, and the near-retiring C. K. Manickavasagam, Subbaraju, is brought in to track him down before his own career quietly fades away. The pursuit sets the tone for a collision between a seasoned lawman and a man driven by an inexplicable compulsion to steal.
Meanwhile, a sharp, morally complex private detective named Diya, Mahima Nambiar, operates on the other side of the law, working for criminals while investigating a separate car theft connected to Malik, the son of the dangerous crime lord Jamalhudeen, Nagineedu Vellanki. A pivotal clue—a video showing Shakti’s face at the train robbery—lands in Diya’s hands, binding her fate to the thief she’s supposed to deny.
Even as Manickavasagam closes in, Shakti executes a bold heist at a flower market. The moment the attempt ends, a chorus of arrests follows, and the flowers’ perfume of innocence quickly fades as the police swarm the scene. To finally corner Shakti, the bank—IDCK—buzzes with a fake public announcement engineered to lure him into the open. The plan initially seems clever, but Shakti’s relentless urge to steal outpaces the ruse, and he brazenly pulls off the heist in broad daylight, right under the nose of the waiting Manickavasagam. The subsequent confrontation leaves a web of tension between the pursuing lawmen and the elusive thief.
Diya’s relentless investigation leads her to Shakti’s house, where she uncovers a hidden room—an archive of every dirty penny he’s ever stolen. The stash tells its own story, and she doesn’t hesitate to call Jamal (the crime lord) to reveal the location of his own wealth. Jagannathan, Jagan, arrives to find Shakti unconscious and Diya in the room, but the truth about their intentions remains tangled. Diya accuses them of criminal complicity, while Jagannathan explains a deeper illness: Shakti has carried a lifelong mental disorder that fuels an overwhelming impulse to take money for no reason at all. To help him fight this compulsion, Jagannathan—a lawman by trade—has steered him toward a dangerous, controlled form of “therapy” by guiding his thefts. Diya’s conscience stirs, and she helps them escape Jamal’s clutches, though Jamal takes the money for himself.
The drama intensifies as Manickavasagam finally traps Shakti and Jagannathan, presenting a murky glimpse of corruption in political circles. He wants Shakti to steal for him again, and the wary thief agrees, tempted by the chance to rob from the powerful. Jamal and his thugs crash the scene, intent on seizing the haul, and a brutal struggle erupts—goons are knocked out, and Jamal himself is wounded. In a tense pivot, Manickavasagam reveals a deeper betrayal: he, too, has dark, corrupt ambitions and plans to keep the money for himself. Before he can act, law officers intervene, deciding to cover up the incident to protect the state police’s reputation. The competing loyalties—justice, corruption, and personal survival—collide in the final stand.
In a sweeping, collective choice, the police opt to turn the stolen funds toward a wider good: 15 lakh rupees will be distributed to farmers across India. The film closes on a note that blends reform with danger, leaving the audience to weigh the cost of law, desire, and the murky ethics of powerful men. The story’s threads—Shakti’s irresistible compulsion, Diya’s moral conflict, and the shadowy politics surrounding Jamalhudeen—coalesce into a provocative tale about crime, cure, and the imperfect justice that emerges when power and money collide.
