Three Pakistani youths throw packets of drugs across the border to India for it to be picked up later. Tejinder "Tommy" Singh, also known as "Gabru" among his fans, is a young and successful Punjabi musician who lives a luxurious lifestyle. Together with an ostentatious crew led by Tayaji and cousin Jassi, he indulges in uncontrolled consumption of cocaine. Tommy is popular for his energetic songs with lyrics that often glorify violence and drug addiction. However, his addiction costs him his music contract and lands him in jail. In prison, he meets two of his die-hard fans who remark how Tommy's lifestyle had 'inspired' theirs, leading them to commit the murder of their own mother. Realizing that his songs have negatively affected teenagers, Tommy decides to change his ways upon release. A few days later, he engages in an altercation with Tayaji and accidentally shoots him, injuring his ear. Tayaji sends Tommy and his crew away to a farmhouse so that he can prepare for an upcoming concert. Working on the farm is a Bihari migrant worker nicknamed Bauria. Bauria's dreams of playing national-level hockey for the country were shattered, so she came to Punjab to work as a laborer. She works for a local landlord who uses agriculture as a front for drug-peddling. One night, she finds a suspicious packet on the farm and realizes that it is some kind of drug. She resolves to sell it but her search for a potential buyer lands her in trouble as she unwittingly contacts the original owners of the heroin. She is captured by the gang of drug peddlers but not before she discards it into a well. As a compensation for their lost drugs, the peddlers forcibly keep her at their house, where she is sexually and physically abused, given drugs, and prostituted to men. Some weeks later, she manages to escape. In the neighboring town lives Preet Sahni, a doctor and activist who runs a rehabilitation center. Sartaj Singh is a junior policeman who knows about the drug smuggling his seniors are allowing. But when it affects his family, as his brother, Balli, overdoses and is brought to Preet's clinic, he realizes the grave situation. Preet and Sartaj decide to find the root cause of the problem together. Balli is admitted into her drug rehabilitation centre against his will. At his concert, instead of singing, Tommy starts preaching. Infuriated by his speech about how one should lead one's life, his fans start throwing bottles at him. Tommy gets angry and urinates in front of the crowd before fleeing. He hides in an old structure and meets Bauria, also hiding. The two share their stories and bond. However, Bauria is recaptured by the same gang. Tommy learns the next day that an arrest warrant has been issued for him because of the public ruckus at the concert. He sets out to find Bauria after realising he is in love with her. Preet and Sartaj find that the driving force behind the drug problem in Punjab is an elderly man called Virender Singh, who has flourished with the support of MP Maninder Brar. The two go to extreme measures to collect evidence against the politician and put together a report to be sent to the state's Election Commission to thwart Brar's campaign for another term in power. Sartaj and Preet fall in love; however, one night, Preet sees a manic Balli trying to escape from her rehab center. On trying to stop him, she is accidentally stabbed in the neck by him. The policemen who investigate her homicide, including senior officer Jhujar Singh, come across the report made by her and Sartaj. Since he is Sartaj's close friend, Jhujar decides to protect Balli by sending him underground. However, he is infuriated when he sees that he too has been named in the drug racket and calls Sartaj. In the presence of the local drug mafia at their farmhouse (where Bauria is confined), a bruised and beaten Sartaj is questioned by Jhujar, who is a key member in the drug racket. Sartaj says whatever he did was for the sake of Punjab. At the same time, Tommy enters the house. Sartaj grabs Jhujar's pistol and shoots the whole gang before freeing Balli. Tommy helps Bauria escape from her captors. Balli kneels and cries in front of his brother, whose face is expressionless. It is shown that the government issued an inquiry into Maninder Brar's activities and there has been a huge crackdown on the drug menace. In Goa, amidst his crew members, Tommy calls Bauria to ask for her real name. Sitting by the beach, she catches sight of a foreigner having fun. Inspired, she utters "Mary Jane
