Central Bureau of Investigations (CBI) has assigned the case of three terrorists to Akram Sheikh (Sunil Shetty). The three terrorists are two brothers Ali and Abbas Ramani (Sanjay Kapoor and Arbaaz Khan), and their girlfriend, Laila (Isha Koppikar). Akram takes charge of this case, and asks his superiors to release Rachit (Ajay Devgan) to assist him. Rachit used to be an associate of the Ramani brothers, but was double-crossed by them. Rachit had escaped from prison and had killed one person, and had been re-captured and is now serving time in a high security prison. Akram does get permission to get Rachit to accompany him. Both of them, together with a team of ace commandos and a scientist Rahul (Aashish Chaudhary) set out to capture the trio, only to find out that the terrorists plan to spread a virus through missiles at various lakes, and water reservoirs in and around the city of Mumbai and it all depends on Rachit and Akram to stop them.
