The story revolves around Inspector Sadhu Agashe (Nana Patekar) from the Mumbai Encounter Squad famous for having killed 56 people in police encounters. It is inspired by the life of sub inspector with Mumbai Police force Daya Nayak.

In 2012 Ram Gopal Varma announced a sequel to the film, to be directed by Nana Patekar.

The section of the Mumbai Police Department responsible for handling the underworld is headed by Sadhu Agashe (Nana Patekar). Sadhu is the city’s best inspector, with an enviable reputation and record of encounter shootings. Though tough, he is a loving husband to his wife (Revathi) and father and also helps his informers and other poor people in times of need. His immediate junior, Imtiyaz Siddiqui (Yashpal Sharma) despises Sadhu to no end; he feels Sadhu intentionally belittles him. Also Imtiyaz is more concerned about adding to his encounter score and therefore ends up killing more than the primary target which is the main reason Sadhu dislikes him. To add to his woes, Imtiyaz is unable to surpass Sadhu’s encounter "score". Enter Jatin (Nakul Vaid), a rookie to this line of policing who manages to impress Sadhu. The inspector takes the newcomer under his wing, further antagonizing Imtiyaz. All of them report to the Commissioner Pradhan (Mohan Agashe) who is a fair and honest police officer.

Daya Nayak (Kannada: ದಯಾ ನಾಯಕ್) is a sub-inspector with the Mumbai police force. He is currently awaiting reinstation following a suspension order based on allegations of disproportionate income by an underworld criminal. He rose to fame for having eliminated more than eighty gangsters of the Mumbai underworld as a member of the Mumbai Encounter Squad, which was created by the Maharashtra Government for tackling the increasing problems of underworld extortion, gangwars, and a terrible law and order situation.

In February 2006, the Anti-Corruption Bureau (ACB) of the Mumbai Police declared Nayak absconding; when he voluntarily surrendered at the court, they arrested him on a non-bailable warrant. Despite multiple raids and an intensive investigation, the ACB could not find any evidence against Nayak as possessing any assets disproportionate to his income. In 2008, a court threw out the ACB's demands for a re-arrest and condemned the ACB for targeting and vilifying a police officer without proof.
