Durjan Singh (Gulshan Grover) is dangerous dacoit of Chambal. For the past 40 years his father used to rein this area. Today it's Durjan Singh's area. He comes to the city with his 20 years' theft stuffs (diamonds & jewels). He meets a don Gajraj (Mukesh Tiwari) and his right hand Ranjeet (Hemant Pandey) and tells them to sell the jewellery, take their 10% and give the rest back to him.
Gajraj goes to a jewellery shop to sell the looted property. Coincidently AD (Aftab Shivdasani) who is running away from police takes Gajraj's van & runs away , further coincidence is the other three character Murari (Rajpal Yadav) Hazari (Sanjay Mishra) & Chetta Singh (Vijay Raaz) who are also running away from the police jump in the same van.
Police are after all four of them for different reasons, AD is dating police inspector PP's (Om Puri) niece Shreya (Priyanka Kothari). PP has decided to get Shreya married to somebody else, that's why AD & Shreya decided to elope.
Here onwards a comic chase starts where sometimes its police and sometimes its Gajraj after them. At a moment the van's tyre bursts because of the bullet fired by Gajraj. The van hits a tree. Here the five of them come to know that there is crores of jewellery in the van and then they run away with it.
To save and hide themselves they reach a dhaba where a gimmick (nautanki Mallika Sherawat) group is doing a show. They all come in police outfit but still Gajraj recognizes them. They then run from there. Somehow they manage to spoof police and Gajraj and reach a village.
This village Madhav Garh is the same village which has the terror of Durjan Singh. Villagers start celebration as they think that police came here to save them from dacoits. AD & gang want to run away from the village but just outside the village is inspector PP, who is waiting for them to come out. Now this team is left with no choice but to fight the dacoits.
The police station of Madhavgarh was demolished by Durjan Singh 15 years back, inspector on duty that time was Ajay Prakash (Shakti Kapoor) who lost his daughter Rajjo ( Shweta Tiwari) and his memory. In the end all unite and fight with Durjan Singh.
Durjan has an elder brother Sajjan Singh (Johnny Lever) who is Gay, he falls for AD, through his help all five finish the terror of Durjan Singh.
