Dibakar Singha (Jeet) is a police sub-inspector from Hridaypur, a small fictional town in the Birbhum district of Bengal. He is loved and respected by the entire town. Arjun Sarkar (Supriyo Dutta) deals in real estate as a cover but is actually a kidnapper and extortionist from Howrah who terrorizes the citizens and has the police on his payroll. Once Dibakar learns of Arjun's actions, he goes after him and kills Arjun's men one by one, including Arjun's younger brother.

During the same time, Dibakar falls in love with Puja (Nusrat Jahan), a beautiful young woman who comes to the city to visit her grandfather on vacation. Dibakar is initially frustrated with the level of corruption in the police department and wants to quit, but Puja manages to instill a feeling of faith in him, telling him, "Fight or you will be a loser." Dibakar continues his hunt to bring down Arjun Sarkar with renewed vigor and proves Arjun to be responsible for 62 kidnappings.

Dibakar is promoted to the head of an anti-kidnapping squad by the Home Minister. He conducts raids on Arjun's hideout and imprisons Arjun's brother Karna under false allegations. To free his brother, Arjun plans to kidnap Puja's younger sister, Diya, but Dibakar foils the attempt by catching two of the kidnappers. Dibakar tricks one kidnapper into confessing that they were hired by Arjun to commit the crime. Dibakar gets the much-needed evidence to prove Arjun is behind all the kidnappings happening in the town. He announces in the press that two kidnappers have been arrested and the money was recovered. The money will be declared as government assets unless someone comes forward to claim it. Many people come forward to claim their stake in the ransom money. Finding himself on the verge of being exposed, Arjun plans to send one of his plants to lure Dibakar to his den and kill him. Dibakar uncovers the real intent of Arjun's plant, who comes to the police station to file a false report, by tracing her mobile phone records to Arjun. He goes to the meeting place along with one of his police officers in disguise and kills Ratan, Arjun's closest aide.

Dibakar then informs Arjun that Ratan has agreed to be a state witness against him. Arjun sends Karna to finish Ratan in the hospital. This is a trick played by Dibakar to force Arjun into committing something foolish. Dibakar kills Karna while Arjun is on the phone with him. This act angers Arjun, who swears to kill all of Dibakar's nearest and dearest. He attempts to kill Puja, but she escapes with a bullet wound in her arm. Dibakar then reveals that his boss, the DSP (Biplab Chatterjee), is Arjun's mole in the police department. Having been exposed, the DSP has no choice but to help Dibakar in exposing Arjun.

Arjun kidnaps the daughter of the Assam Home Minister and takes her to Jharkhand. Dibakar pursues him and kills Arjun.

At the police ceremony to congratulate Dibakar, he announces that he has decided to return to his village and has finished what he came to do in the city. Puja is shown accompanying him on this journey.
