Romeo Rajkumar, portrayed by Shahid Kapoor, is a directionless young man who finds himself in the small town of Dhartipur, a place ruled by two rival opium drug lords: Shivraj Gurjar, played by Sonu Sood, and his nemesis Manik Parmar, a character brought to life by Ashish Vidyarthi. This volatile territory is under the shadow of a Mafia don, Ajit Taaka, who orchestrates operations from Hong Kong.
As tensions rise, Shivraj decides to hike the price of raw opium, which is eagerly procured by Taaka. The price increases by an astounding 300%, and amidst this chaos, Shivraj declares that his goons have raised their salaries from Rs 5000 to as much as Rs 20000. This blatant power play irks Taaka, leading Shivraj to threaten direct sales to the market, effectively cutting off Taaka's supply. Meanwhile, Qamar Ali, played by Mukul Dev, remains loyal to Shivraj.
After a series of events, Rajkumar's fortunes change when he secures a job with Shivraj by preventing an opium truck from being looted by Parmar's thugs. Though initially untrusted by Qamar, Rajkumar soon earns Shivraj's confidence after saving him from a cleverly planted IED on the road, showcasing his quick wit and bravery.
However, Rajkumar's life takes a significant turn upon meeting the intelligent and captivating Chanda, portrayed by Sonakshi Sinha. During a mission to eliminate two of Manik's men, Rajkumar allows himself to be distracted by his infatuation with Chanda, leaving Qamar to handle the task solo. A crooked policeman manipulates both Parmar and Shivraj, setting the stage for a meeting where betrayal looms. Just as Parmar prepares to double-cross Shivraj, Rajkumar heroically intervenes, thwarting Parmar's plans and emerging victorious over his underlings.
Caught in a whirlwind of emotions, Rajkumar risks his life to rescue an elderly man from a burning building, motivated solely by his feelings for Chanda. Yet, despite his numerous brave acts, he struggles to draw her attention. Eventually, he confesses his love for her, unaware that she is the orphaned daughter of Manik Parmar.
Through continued persistence, Rajkumar captures Chanda's heart, but their budding romance faces an ominous threat when Shivraj and Parmar strike a deal that forces Chanda into an unwanted marriage with Shivraj on the auspicious day of Dusshehra. Determined not to let this happen, Rajkumar bravely declares his love for Chanda amidst the looming wedding plans, vowing to marry her in front of Shivraj on the very same day.
Shivraj, intent on preserving his reputation, plots to eliminate Rajkumar before the impending wedding. But Chanda and Rajkumar outsmart Shivraj, with Chanda challenging Shivraj to defeat Rajkumar before claiming her. The stakes grow higher when Rajkumar retaliates against Parmar for his abuse toward Chanda.
When Shivraj orchestrates an encounter to get rid of Rajkumar, a shocking twist unveils that Rajkumar has been working for Don Ajit Takka, with a master plan to take over the drug trade controlled by both Shivraj and Parmar. However, unbeknownst to Rajkumar, Shivraj and Takka conspire against him by leading him to steal an empty truck full of drugs, ultimately resulting in his brutal demise.
As Shivraj's wedding celebrations commence with Chanda, an unexpected turn of fate reveals that Rajkumar is still alive—rescued by Qamar, a former ally. Qamar aids Rajkumar in his pursuit of Chanda, leading to a showdown where Rajkumar ultimately confronts Shivraj. In a climactic battle, Rajkumar delivers a devastating blow to Shivraj, closing the chapter on his tyranny, and later dispatches Don Takka as well. The story culminates with Rajkumar, though battered, walking away hand in hand with Chanda, united in happiness amidst the chaos around them.
