Uday Shetty and Majnu Pandey end a life of crime and become honest businessmen, settling in Dubai. Two con-women from India, Poonam and Babita, present themselves as Maharani Padmavati and Rajkumari Chandni of Najafgarh in order to con Uday and Majnu of their money. Babita causes the two men to fall in love with her, thus getting them to finance herself and Poonam's luxurious lifestyle. Later, it is revealed that Uday has another sister Ranjana  from his father, Shankar Shetty's third marriage and Majnu and Uday are emotionally blackmailed by Uday's father into arranging the marriage of Ranjana and are also forced to do so as Poonam makes that one of her conditions for getting Babita married to either one of them.

The movie then shifts to Dr. Ghunguroo who has found out that he has a stepson from his wife's previous marriage that he was unaware of, Ajju. Ajju is a local goon of Mumbai, where Ranjana studies. Through a chain of hilarious events, they both fall in love with each other. Meanwhile, Majnu and Uday arrange the marriage of Ranjana with the step-son of Doctor Ghunguroo, not knowing that he is a goon. However, at the engagement ceremony, Majnu reveals the truth of Ajju, to which Ajju resists with a fight, threatening to marry Ranjana without any of the brothers' consent.

In order to keep Ajju at bay, Uday and Majnu visit Wanted Bhai, (Naseeruddin Shah), who is an infamous blind don. They also return to their old, violent ways in order to kill Ajju. The brothers are shocked to find that Wanted's son Honey (Shiney Ahuja) likes Ranjana and would like to marry her. They decide to arrange the marriage of Ranjana to some other decent man, in order to sidestep Ajju as well as Wanted's son. However, due to Ajju and Dr. Ghunguroo, who are in league with Babita and Poonam, they are caught by Wanted Bhai, who summons them to his island.

There, Ajju and Dr. Ghunguroo try to convince Honey that he no longer loves Ranjana and that Babita is his true love. Meanwhile, Uday and Majnu try to kill Ajju, but are frightened at the graveyard in a ghost act planned by Dr. Ghunguroo, Ajju and Ranjana. Unbeknownst to all of them, their activities have been recorded by closed-circuit television, causing Wanted Bhai and Honey to plan to finish them off. However, in a hilarious climax scene, Honey is kidnapped by all of them and they escape towards the desert where they are chased by Wanted Bhai. In the midst of saving himself, Dr. Ghunguroo pushes Wanted Bhai, causing him to faint. Meanwhile, a group of camels heavily march there. Ajju is successful in saving Wanted Bhai from the stampede of camels, and restoring his sight. Wanted Bhai himself, as a form of gratitude, arranges the marriage of Ajju with Ranjana, calling Ajju his 'second son’.
