A slick diamond robbery takes place in India. The robber is none other than Rocky (Chunky Pandey) who's the nephew of Chowksi (Gulshan Grover), a Don based in London. Chowksi tells Rocky to sell the diamond to his brother Lalwani (Asrani) in Dubai. Lalwani is a dealer of smuggled gems and jewellery. But he warns Rocky to stay away from guns and gambling, which is his weakness, to ensure nothing goes wrong.

Bhabhi's son dies in an accident two years back, which completely shakes her. Munna then finds Raja, who is a look alike of her dead son. Munna hires Raja to play her son for a handsome amount. Raja is anyway a crook and does anything for money. He agrees to do so.   Along with this, Raja is now planning the robbery with Choubey and Tina. They hire Pattu (Johnny Lever), who's famous for his driving skills, to help them flee after the robbery.

When Rocky lands in Dubai, he gets in touch with Moscow Chikna to buy guns. But he is well aware who Rocky is. He asks Rocky not to pay for the guns instead bet on his behalf at J.D's illegal bookies. Moscow then instructs Choubey, Raja and Tina to kidnap Rocky outside the bookies.  Outside the bookies when they do not get hold of anything they plan to rob the bookies. But again they come out empty handed. As they come out they are over whelmed to find Rocky. They kidnap him and take him to their junk shop. Moscow Chikna shoots Rocky and takes the diamond away leaving them with the body.    Meanwhile J.D learns that some men attempted to rob his bookies. Agitated he comes to Choubey's junk shop. There he finds out that Rocky was the one who was carrying the precious diamond. He tells Choubey and gang that he will spare them only if they get him the diamond.  Chowksi who comes down from London realizes that Rocky is missing. To find him he hires G9 (Jackie Shroff). Now here all the stories inter cross.  Now with all of them caught up together in this chase, the story takes a comical twist. A lot of breaking bones for stealing stones end up this bout with a complete knockout comedy!
