Dr Ram Prasad Ghayal (Amitabh) is a surgeon whose scalpel proves to be a magic wand. He has a wife called Janaki (Dimple) and a brother called Bharat. Bharat is in love with a dancing doll Renu (Karishma) whom the baddie`s brother (Deepak Tijouri) also loves. Bharat, an architect refuses to sign a power project involving heavy kickbacks and heavier displacement (with so many scams in the air, what can one expect the plot to be). He is implicated in a plot and sent to jail. Unable to bear this humiliation, he commits suicide and Renu marries Deepak instead of repenting her beloved`s loss. Now is the time for our `Mrityudaata` to avenge the loss of his wife and his brother. He trades his scalpel for a machine gun and apron for a commando coat and cap.
