Bobby Deol plays a petty thief Sham who is on the run with a thirty crore diamond. When cops get too close to nab him, he hides the diamond in an under-construction building. Cops arrest Shaam and put him behind the bars for two years. After he is released from the prison the first thing Sham does is to go back to that construction site where he had hidden the diamond. To his utter shock, he finds out that the building has been converted to a police station. Anyway, the indomitable Shaam decides to get his hands on the diamond. He enters the police station impersonating as inspector Ram. In the police station, he encounters inspector Ranjita (Bipasha Basu) who falls in love with him without ever suspecting that he is a thief. For Ram getting the diamond is not easy, as he has to outfox the ACP Ranbir Singh (Paresh Rawal) and the psychotic and ever-suspicious Inspector Pande (Om Puri). Besides these two, there is Kajal (Shilpa Shetty) the pampered daughter of ACP who keeps giving Ram a tough time. And last but not the least is small-time goon Tito (Ashish Vidyarthi) who keeps switching from one avatar to another to dupe Ram and other cops. In this mad rush for the valuable diamond who will his hands on the booty?
