A police operation targets Ronnie, the leader of a criminal syndicate. His own younger brothers Lama and Ujan betray him by taking him hostage and exposing him to danger, using the captured leader as a bargaining chip. The moment hints at a prophecy that a bad man will rise to bring Ronnie down.

Raja arrives in Kolkata with his sister Disha. He brings his gentle nature to a rough city and helps reform the local hooligan Kolkata Kaali, who becomes an ally. They find a new house with Kaali's help, and Raja soon starts a job as a driver.

Raja's driving work leads to his first client, the lawyer Alia. An incident at work lands him in trouble with Alia, and he is fired from her firm; Alia allies with Raja's taxi company boss to seek revenge, but their plan evolves and she eventually befriends Raja.

Alia's brother falls in love with Disha, adding a personal subplot to Raja's life. This romance intertwines with the growing tension between Raja and the city’s criminal underworld.

The police commissioner holds a conference with drivers, urging them to report any syndicate activity in the city. The meeting raises tension and places Raja on the front line of the crackdown. Raja begins to keep an ear out for suspicious movements tied to the syndicate.

Raja spots the syndicate's activities and reports an arms and drugs smuggling case. Ujan captures him, but Raja escapes and brutally kills Ujan and his men, signaling a brutal vendetta and marking him as a target for the syndicate.

Lama arrives in Kolkata with a technical team to investigate Raja's murder and locate the killer. They trace Raja's mobile signal to a city tower, narrowing the search. In a climactic raid, Raja ambushes and kills Lama and his attack squad.

A year ago, Sultan—a terrifying mercenary—was arrested but freed when he saved the police from a rival gang in exchange for money. This backstory gives context to Raja's identity and the criminal world he navigates alongside Disha.

Raja is stabbed by opponents after a business loss, and Disha helps him by getting him admitted to a hospital, lying that Sultan is her brother to secure him treatment. Disha and her blind parents are pressured to sell their house, so she and a friend hire Raja for protection. Raja betrays them for money, but the family remains connected to him for a time.

Raja eventually helps rescue Disha and 99 other girls from a trafficking ring led by Ronnie. In the process, Disha's parents are killed and Disha herself is injured, eventually losing her memory. Raja vows to kill Ronnie and to protect Disha.

Ronnie travels to India to uncover who killed his brother and hires Disha to draw a forensic sketch of the murderer by using an injured victim. He intends to locate the killer through the sketch and Disha's testimony, tightening the noose around Raja.

Ronnie abducts Disha and Raja pursues him. Without giving away everything, Raja confronts Ronnie, kills him, and rescues Disha, finally fulfilling his vow to end Ronnie's crime syndicate.
