Barely in his teens, Sonu works as a servant in the palatial house of Mr. Nath, his wife and step-daughter, Nisha. One day while ironing Nisha's birthday dress, Sonu accidentally burns it, earning the wrath of Nath, who places the burning iron on Sonu's back. Thereafter Sonu is arrested by the Police and taken away. Years later, Sonu has grown up, calls himself Shankar, and makes a living as a bounty hunter.
