One day, a police officer sees Haricharan, gets impressed by his kind and honest nature, he gives him a job. Soon, Haricharan earns more and their financial condition improves. Their son grows up.

Years later, Aarti dies. Haricharan is employed in a company. His employer's daughter is deaf and mute and the employer wants to fix Haricharan's son's wedding with his daughter. Haricharan declines as his employer is richer than him but the employer convinces him. Seeing the daughter, Haricharan is reminded of Aarti and agrees for the wedding. The son opposes the wedding as she is deaf and mute, much to Haricharan's distress. He berates him, and reminds him that even his mother was mute.
