Disappointed with life, PRAAN is on the verge of committing suicide when the popular professor of the village intervenes and prevents him from doing so. He gives him shelter in his own home and also the message of a new life - a life devoted to service of mankind based on the immortal gospel of the East, "Live and Let Live".
Dr. REKHA, daughter of a wealthy man of the village was once saved by PRAAN from accident. Rekha tries to compensate Praan for his kind act but he not only refuses to acept any money but is much astonished that rich people can valuate life in terms of money. Rekha is fascinated by his refusal and they continue meet each other while love grows between them.
At this stage the Jagirdar of the village comes in their way. After running the life of a poor girl MEENA, he now tries to seduce Rekha. Homeless and helpless Meena was sheltered by the Professor and Praan. Meena and Praan live like sister and brother.
Jagirdar becomes Praan's enemy, having come to know that Rekha loves him. He starts a false propaganda against Praan and wins over the villagers to his side by foregoing some extra revenues and brings about separation of Praan and Rekha.
Ultimately, however, the Professor succeeds in proving to the villagers that it was the Jagirdar and not Praan who had seduced Meena. Sympathy of the villagers now turns against the Jagirdar. They march in procession under the leadership of the Professor and reach the Jagirdar's house and demand justice. Failing in his further tactics the Jagirdar desperately shoots Meena. Praan pounces upon the Jagirdar and in the fight which ensues he looses his life and the Jagirdar is arrested.
Rekha, however, rises to the occasion. Life without Praan has no charm for her, but inspired by the Professor's philosophy and advice she is encouraged to enter a new life... the life of service to which Praan was devoted until the last breath of his life.
The Professor gives her the same message which he had given to Praan- "Live and Let Live" and exhorts her to continue the unfinished task of her beloved Praan.
