Uday Shetty and Majnu Pandey end a life of crime and become honest businessmen, settling in Dubai after being duped by Uday's brother-in-law Rajiv. Two conwomen from India, Poonam and Babita, pose as Maharani Padmavati and Rajkumari Chandni of Najafgarh in order to con Uday and Majnu of their money. Babita gains the attraction of the two men, 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 Shankar into arranging the marriage of Ranjana and are also forced to do so as Poonam makes it one of her conditions for getting Babita married to either one of them.
The film then shifts to Rajiv's uncle, Dr. Ghunguroo, who has found out that he has a step son named Ajju from his wife's previous marriage that he was unaware. Unlike Rajiv, 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, causing Ajju to retaliate with a fight, threatening to marry Ranjana without any of the brothers' consent.
Expecting to keep Ajju at bay, Uday and Majnu visit Wanted Bhai, 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 Bhai's son Honey 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 Bhai'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.
At the island, Ajju and Dr. Ghunguroo try to convince Honey that Honey 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 CCTV camera, 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'.
