Dwarkanath and his wife were separated from their child, a son named Shankar, when they attended the Khumbh Mela in Central India. Years later they are still awaiting his arrival. Notorious con-man and gangster, Sunderdas, comes to know of this, and hires a look-alike named Kundanlal, who meets with Dwarkananth, and is accepted immediately.
