The serial killer is dubbed 'Stoneman' by the media has just claimed his fifth victim and the case is still of little interest to the
Bombay Police. But to suspended sub-inspector Sanjay Shelar (Kay Kay Menon), this killer poses an opportunity. Sanjay hopes to track this killer down and thus, possibly find an entry back into the police force. With the secret aid of his patronizing superior AIG Satam (Vikram Gokhale), Sanjay takes up the arduous process of tracking this killer down. But the official police investigator of the case Inspector Kedar Phadke (Arbaaz Khan) clashes incessantly with Sanjay as both of them, separately, delve deeper into the case. Sanjay on the other hand is determined to find the stoneman. He takes the help of his informer. His wife Manali (Rukhsar) is upset with him and thinks that he is having an affair with another woman. Sanjay goes on with his investigations. One night someone throws a stone inside Sanjay's house through a window. Manali thinks it to be the mischief of some boys of the locality but Sanjay feels it is the stoneman. Another night the stoneman tries to kill a beggar sleeping on the roadside but is saved by Kedar and some patrolling policemen. Sanjay and his car is spotted by Kedar that night. Sanjay finds that his investigation house has been visited by the stoneman as sees vermilion spread everywhere.
Sanjay contemplates a possible danger to his wife asks her to leave for her village. He rushes to the station to get her rail ticket where he encounters the killer but before he can catch him Kedar shoots him thinking him to be the killer. Sanjay escapes and the incident brings him closer to his wife. He suspects the killer to be a policeman who is a tribal performing an impotency ritual and asks the informer to tell this to Satam. Kamle (Virendra Saxena) turns out to be the killer and attacks Sanjay, but both are saved by the police. Kamble is arrested and the matter is closed. In the end it is shown that the man with a voice similar to Satam is performing a ritual and asks a person to give him nine offerings of humans and this time to kill people in Calcutta.
