Maharani, a transgender brothel owner, runs a sex trafficking operation in Bombay. She employs several women including Pooja and Chanda. Ravi Kishore Verma, a taxi driver, meets Pooja before she is taken in by Maharani, and his friend Gotya is in love with Chanda. Ravi previously witnessed his sister Roopa plunge to death after being diagnosed with STD. She had eloped with her lover who sold her off at a brothel and forced her to become a prostitute. The incident leaves Ravi emotionally disturbed and plagued by insomnia and violent episodes.
One day, Ravi meets Inspector Irani, a police officer he recognizes from a newspaper article. He gives Irani a ride and refuses payment. The officer tells him to reach out if he ever needs help.
Ravi meets Pooja again as she tries to flee the brothel of Maharani and tries to help her in vain. He procures his life's savings, a meager sum of thirty thousand rupees from Salim Bhai, his taxi's owner and takes out Pooja for one night, posing as her customer. He does so with the help of his friend, Gotya, and a pimp, Gullu. Gotya, however, is held as collateral under Maharani's orders in case Pooja is not safely returned. They roam around Bombay and spend some romantic time with each other, during which Ravi tells Pooja that he loves her and will keep on coming back to the brothel for her every night (presumably—so that she is not sold to other customers).
The next night, Ravi mortgages the taxi and goes back to the brothel. He is, however, chided by Maharani who suspects he's either mad or in love with Pooja for offering high sums of money for her on consecutive nights. She also tells Ravi that since she has been running this business for the past thirty years, she knew when Pooja came back in the morning that Ravi did not sleep with her. After much argument and requests from Ravi and Gotya, Maharani agrees to let him spend the night with Pooja under the condition that he has sex with Pooja in front of her. Ravi agrees, but stabs Maharani, escaping with Pooja in the ensuing chaos. Gotya also grabs his girlfriend Chanda and escapes. They run away to a distant location where Gotya and Chanda get married in a temple with the blessings of Ravi and Pooja. All four come back and take refuge with Salim Bhai.
In the meantime, Maharani's henchmen find the pimp and break his legs. Salim Bhai advises Ravi and Gotya to enlist police protection and Ravi decides to approach Inspector Irani. He assures them of his help and asks them to meet him in the parking lot of an apartment complex at a scheduled time. However, when the four reach there, Maharani and her henchmen are already waiting and attack them with firearms. As the four try to escape, Gotya and Chanda are both shot and Ravi manages to escape with Pooja in Irani's police jeep. Once they reach safety, he calls up Irani and warns him that he will have to pay heavily for his betrayal.
Pooja is, however, captured again by Maharani, after Ravi is tortured and left for dead. Ravi, remembering that the fate of his sister and Pooja are the same, regains his lost strength. He fights his way back to Maharani by killing Inspector Irani and setting ablaze Maharani's brothel, finally killing Maharani and rescuing Pooja. Ravi is jailed for taking law into his hands. After his release from jail, Pooja and Ravi are united again.
