Insaaf: The Final Justice (1997)

A gangster named Shah who owes allegiance to the Janardhan gang is killed by Chimanbhai. Although Janardhan is in prison, he ensures that Chimanbhai is notified of his anger and vengeance. Chimanbhai arranges a meeting with Janardhan and kills him. Some schoolchildren and their teacher Aarti Singh, who are at a picnic nearby, witness this, but Chimanbhai and his men hunt them down and kill them all. The entire country is shocked by this killing, and the police are under pressure to apprehend the killers at any cost. Aarti's brother, Police Inspector Vikram Singh, also assists in finding the killer and gets his girlfriend Divya to pose as Aarti to lure the killers out into the open. This does get some results--just not the ones Vikram and Divya hoped for--and they're now on the run, not only from Chimanbhai's gangsters but also from corrupt policemen, and a Member of Parliament who is also involved, and will do anything within his power to ensure that both get killed.
