prove his innocence) is stolen by Jasjit in order to track down Deepu and Munni. He meets Vijay and Roma who team up with him. However, the trio learn that Malik himself is actually Vardhaan who captured the real R.K. Malik (Pinchoo Kapoor) and posed as the latter to cover his crime, and that Vardhaan was the one who had murdered DSP D'Silva during the raid-up and had already exposed Roma's identity to the gang members, before having them kidnap Deepu and Munni so that the trio can surrender themselves and the diary to Vardhaan. After being captured by Vardhaan, Jasjit is reunited with Deepu and Munni and manages to escape the hideout with them, thanking Vijay for taking care of his children. Meeting up in the same graveyard where Don was buried, Vardhaan and his gang members who are holding Deepu and Munni hostages, have a long standoff with Vijay, Roma and Jasjit, resulting in Vardhaan grabbing the diary from Roma and throwing it in a fire. Eventually, he calls Inspector Verma and the police to the scene to have the trio and the gang members arrested so that he can get away scot-free. However, anticipating the possibility that Vardhaan would try to escape, Vijay cleverly reveals that the diary that he had thrown in the fire was actually the blank one that he had switched, just as he hands over the real diary to Verma, exposing Vardhaan's identity and occupation to the police. Eventually, Vardhaan and the gang members are arrested and sent to prison for their crimes while all charges against Vijay are dropped. The film ends with Vijay, Roma, Jasjit, Deepu and Munni happily walking away from the police station, satisfied that they took down Vardhaan and his gang members for good.
