The Indian Army assigns this matter to Colonel Ranvir Singh Ranawat (Ajay Devgn), who along with his men, apprehends and arrests the ring-leader Baba Zaheer Khan (Mukesh Tiwari). The Colonel takes one of his subordinates, Jaideep Rai (Abhishek Bachchan) to task, as nine soldiers were killed due to his negligence and asks him to resign. A terrorist group, Al-Tahir, recruits a group of men to try to evacuate their leader Baba Zaheer from Army prison, albeit in vain as their plans are thwarted by Jaideep, who is now an Assistant Commissioner of Police (ACP) in the Anti-Terrorist Squad (ATS) in Mumbai city.

The professor bribes two corrupt officials of the Mumbai Airport to sneak in Guns inside the flight as they never go through the security checks. In a cross-fire between Mumbai ATS, ACP Jilitants' gets the police, this group hijacks an Indian Airlines plane, en route from Mumbai to Kathmandu, with Jaideep's fianceè, Nandini (Bipasha Basu), an in-flight supervisor, and Captain Basheer Ali (Pankaj Dheer), ACP Jaideep's foster father on board. The plane, with 107 passengers and crew, is re-routed to Kazan in Pakistan-administered Kashmir where they are met with more armed terrorists as well as the Pakistani Army. Together, they demand the release of Baba Zaheer in exchange for the lives of the passengers. ACP Jaideep soon recollects from his last conversation over the phone with Nandini that one of the two airports ground-staff did not leave the flight till the last moment of its departure. Jaideep apprehends him to which he confesses of sneaking in guns and other ammunition into the flight. The Indian Government makes a failed attempt to convince the Pakistani Ambassador (Arun Bali) to either send the Pakistani Army or let the Indian Army enter Pakistan-controlled Kashmir to rescue the civilians on board the flight. The Army and the Indian police collaborate and both Ranvir and Jaideep are asked to work together. Ranvir is weary of Jaideep's capabilities, since Jaideep is investigating Ranvir and his men — who are suspected of supplying arms and ammunitions to terrorists and Pakistanis. The duo nevertheless works out a plan to free the hostages and apprehend the terrorists. What they do not know is that their plan has already been compromised, and they may well be headed to their respective deaths. After a major gun-battle, Ranvir and Jaideep manage to capture Baba Zaheer again only to throw him out of a flying Army helicopter, after the flight has taken off from Kazaan in Pakistan-administered Kashmir.
