The CBI learn from a witness a conspiracy to asassinate the Prime Minister, Rajwansh Shashtri (Girish Karnad). The witness tells them that there are four main people involved in this conspiracy. CBI head Vikram Dutt (Kulbhushan Kharbanda) assigns officer Dev Malhotra (Sunil Shetty) to the case. When Dev kills one of the four guys in the conspiracy, he learns that the whole conspiracy began in Ootie. So he goes to Ootie disguised as a school teacher (here is where they copied Kindergarten Cop a little bit) and there he meets another CBI officer in disguise, her name is Komal (Shilpa Shetty).
The principal of the school that Dev teaches in is Mahendra Pratap Gujral (Suresh Oberoi). M.P. Gujral, Colonel (Mohan Joshi), and a "chaprasi" in the school are the other three guys who are planning to kill the P.M. Dev comes to know of this. The rest of the film is how he catches criminals and saves the P.M. before October 2nd, the date when the P.M. is planned to be killed. Then Dev learns that the main hand behind the conspiracy is none other then M.P. Gujral, whose real name is Suraj Singh. Then the "real" suspense is revealed.
