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.

On the other hand, the local mafia in Dubai, Moscow Chikna (Arbaaz Khan) is torturing Choubey (Paresh Rawal) because he was unable to return the money he had loaned from Moscow Chikna. Choubey owns a junk shop and was facing major loses. He gets information about the diamond robbery from one of his informants. He is also made aware of the involvement of the International mafia Chowksi. To keep a low profile, Moscow Chikna asks Choubey to get the diamond for him, only after which he will leave him. Choubey gets along with Raja (Shahid Kapoor), a fast robber, and Tina (Ayesha Takia) who’s his niece to plan the robbery of the precious diamond.

Luckee (Viveik Oberoi) and Bob (Suresh Menon) own a small video and game parlour in Dubai. To earn a little extra money they also promote new fighters who want to take part in illegal boxing matches in Dubai.

J.D (Zakir Hussain) is a big underworld Don, who controls all of Dubai's illegal gambling and fights. J.D's men also get girls from India to Dubai promising them jobs. But once in Dubai, the girls are forced to work in dance clubs. One of them is Payal (Sameera Reddy). But Payal manages to escape from there. J.D is very upset as he really likes her. He orders his men to find her.

J.D’s men are looking for Payal in the market place. Right there are Bhabhi (Sharmila Tagore) and Bhaiya (Om Puri) who are quiet shaken when they see Payal being taken away by the men. They call Munna (Sunny Deol), who is Bhaiya’s brother, to save her. Munna enters in a heroic manner and knocks them out. They all then take Payal home. Payal eventually falls in love with Munna.

Munna owns a garage and is known for his strength and power. He is strong and very impulsive. He can knock out anyone and just about anyone in one blow! He doesn't think before getting into a fight because he is aware of his potency. Because of this, he is also approached by Luckee to wrestle with some of the strongest men around.

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 ends up this bout with a complete knockout comedy!
