The film opens with the kidnapping of three nuclear scientists by Pralayanath Gundaswami as he plots to build missiles for an invasion of India. The kidnapping raises the stakes of national security and sets the mastermind's ambitions in motion. The authorities immediately begin a high-priority operation to locate the missing scientists.

The honest Deputy Inspector General Rudrapratap Chauhan is murdered by Pralayanath Gundaswami as part of his hitlist. The crime signals the reach and ruthlessness of the mastermind. The investigation notes that Rudrapratap's son, Sanjay, is the sole witness to the murder.

Sanjay is identified as the only witness to his father's murder, forcing him into the center of the case. Police intensify efforts to connect the missing scientists to the killer and his broader plot. His status as a witness also makes him a target for Pralayanath's operatives.

With the case expanding in scope, the police enlist Brigadier Suryadev Singh to take charge of the operation. He begins coordinating with other officers and devising a plan to counter Pralayanath's threat. His leadership becomes crucial to the pursuit of the mastermind.

Suryadev forms an alliance with the hot-headed Inspector Shivajirao Wagle, who has spent time on suspension due to his temper. The two officers bring contrasting styles to the mission, pushing forward despite friction. Together they vow to stop Pralayanath's scheme before it escalates further.

On New Year's Eve, Sanjay and his friends discover Radha Tandel severely injured on the beach after an attack. They rush her to the hospital, but flee when hospital staff summon the police. The incident sets off a chain of discoveries that reveal a larger conspiracy.

Police locate a dead girl on the beach, and investigators trace Sanjay by the wallet that falls at the scene. He is charged with murder and attempted rape, complicating the case and turning the spotlight onto his involvement. The charges threaten to derail the pursuit of the nuclear plot.

Pralayanath attempts to assassinate Suryadev by planting a bomb in his car. The high-tech car enables a dramatic escape, and the explosion is reported as Suryadev's murder before the truth comes out. Suryadev survives and later reveals his escape in a television interview.

After surviving the attack, Suryadev explains how he escaped and survived during a TV interview, countering Pralayanath's propaganda. The broadcast strengthens public faith in the investigation and energizes the pursuit of the mastermind. The confrontation between the two sides shifts to a public stage.

Pralayanath tries to kidnap Professor Khurana again, but Suryadev and Wagle foil the attempt. The failure narrows his options and exposes the fragility of his operations. The standoff tightens the circle around him as the chase continues.

Pralayanath then targets Sanjay and his friends, but one of his companions sacrifices his life to save Sanjay on the eve of Raksha Bandhan. The sacrifice underscores the personal costs of the pursuit and heightens the determination of Suryadev and Wagle. The criminal network remains dangerous and relentless.

After the failed kidnapping, Pralayanath takes the fuse conductor to activate his missiles, escalating the threat. Suryadev and Wagle track him using their trans-meter and begin closing in on his location. The fuse conductor becomes the pivotal object around which the final chase revolves.

Suryadev and Wagle use their trans-meter to locate Pralayanath and his hideout, closing in on the mastermind's position. The pursuit intensifies as the heroes cut through obstacles to reach the source of the threat. The tension peaks as the final confrontation nears.

In the climactic battle, Suryadev disables the missile system by removing the fuse conductors and guns down Pralayanath Gundaswami. Wagle finishes off Pralayanath's son, erasing the criminal network's leadership. The film ends with the 15 August programme concluding successfully and peace restored.
