The police investigate this, but are baffled, and unable to solve this mystery. The woman is Seth Durgadas' late wife. The police interview Seth Durgadas but nothing comes of it. In the meantime, Ranjeet (N.A. Ansari) rescues Sabita (Shakila), the only daughter of Seth Durgadas from the clutches of a tiger, and himself is disfigured for life.
