Based on the 1991 Lokhandwala Complex shootout, a real-life gun battle between gangsters and the Mumbai Police, it stars Amitabh Bachchan, Sanjay Dutt, Suniel Shetty, Vivek Oberoi, Arbaaz Khan, Tusshar Kapoor, Rohit Roy, Aditya Lakhia, and Shabbir Ahluwalia in pivotal roles.

Khan explains to Dhingra that he hand-picked 27 of Mumbai police's best-enlisted men and officers to help combat crime, borrowing the concept from the LAPD SWAT team.

Following Operation Blue Star in 1984, several Sikh extremists fled to Bombay and began establishing a base in the city, engaging in violence, extortion, and other subversive tactics.

Maya's ambitions are fuelled by his mother (Amrita Singh), growing to the point where he wishes to assert his independence from Dubai and take over Bombay for himself.

When prominent city builder Wadhwani (based on Gopal Rajwani, the owner of the building the movie was set in) refuses to pay Maya Rs.

Tipped off by an informant (who, Dhingra alleges, called from Dubai), Khan learns that Maya's gang is located in a flat at Swati building in Lokhandwala.

During the subsequent shootout, Maya's gang tries to escape by various means, contacting Dubai, bribing a senior officer to intervene on their behalf, and even firing a rocket-propelled grenade as a distraction, but fail.

There was a chase sequence with Sunil Shetty and Arbaaz Khan playing cops, and Ravi Gosain (Aslam Kesai) through Lokhandwala.
