A. M. Rajah

Raja, the son of a rich man who was cheated of his wealth by Jambu, grows up in an orphanage. He becomes a famous poet in the city with the help of Jambu's family, unaware of his past.

Chandru (Sivaji Ganesan) has a sister (Rajam) who is married to a handsome Ravi (Balaji). But her in-laws insist on a diamond necklace, without which she cannot join her husband. So, Chandru steals a diamond necklace with a locket and then his sister joins her husband. He and his mother (Shanthakumari) move to Madras where he finds a job in a company owned by a wealthy man (Ranga Rao). He falls in love with his daughter (Saroja Devi). One day, the necklace falls down and the locket opens, revealing a photograph of a young man. The husband and the others at home want to know who the person is. She says she has never seen him. But suspecting the worst, she is sent back to her parental home.

Bhaskar (Akkineni Nageswara Rao) and Vasanti (B. Saroja Devi) are college mates who clash when she complains to the college principal about a love letter he sent her. Later on realizing her mistake, Vasanti apologizes to him and the two fall in love. Vasanti's elder sister, Geeta (Krishna Kumari), supports the family by stitching clothes.Bhaskar rents the room upstairs in their house. He falls ill and in nursing him, Geeta falls in love with him. She confides her love to Vasanti, who decides to sacrifice her love for her the sake of her sister and convinces Bhaskar to marry Geeta. Bhaskar initially neglects Geeta. On finding out, Vasanti writes to him that their sacrifice, made for Geeta's happiness, would mean nothing unless he is a good husband to Geeta. Bhaskar relents and Geeta and he have a son. Vasanti joins them and Geeta suspects that there is something on between Bhaskar and Vasanti and makes Vasanti leave the house.

Baskar and Vasanthi are college-mates. A naughty girl creates misunderstanding between them, and an enraged Vasanthi complains to the college dean, who immediately dismisses Baskar. Now left homeless, Baskar however manages to get employed at a tea company, and gets to stay with his close friend Sampath. Vasanthi approaches Baskar and apologises for her cruel act. Baskar forgives her, and they both fall in love. Vasanthi lives with her mother and her elder sister Geetha who is unmarried. Baskar rents the vacant portion of their house. Over time, Vasanthi passes her exams and gets employed.
