Zamindar Bhujangarao (Gummadi) has two sons. The elder son Raghunath Rao (Akkineni Nageswara Rao) born to his first spouse is a retard. After her loss of life, he married Rajeswari (Santha Kumari) and the couple has a son Nagendra Rao / Naagu (Jaggaiah) a person of vices. Impressed by the way in which Padma (Savitri) a village woman confronted Naagu when he threatened to take their farm lands, the Zamindar fixes Naagu’s marriage together with her. However Rajeswari vetoes the alliance and suggests to carry out her marriage with Raghu. After marriage, Padma learns that Raghu turned a retard as a result of opium-fed throughout his childhood to place him to sleep by the maid, Ayamma (Vijayalakshmi).
