Output: Rajalingam is the only son of Ramalingam, the zamindar of Kalathur. Kannamma is the daughter of Murugan, a farmer of the same place. On the zamindars advice, Murugan sends his daughter to Madras for higher education. While returning from Madras, Kannamma meets Raja in the train. Noticing her respect and awe for the zamindar, Raja calls himself an electrician visiting the palace. They fall in love. A few days later, Kannamma learns the truth and to reassure her, Raja marries her secretly in a temple. Two days later, Raja has to go abroad for higher studies. During his absence, Ramalingam learns of the marriage and orders Kannamma to forget his son. Moved by the zamindars feelings, Kannamma promises never to mention their marriage to anyone. Kannamma is now in the family way. Ramalingam arranges for the stay of Murugan and Kannamma in a nearby town, Sevalpatti. Murugan, who is ashamed of Kannammas love affair, leaves Kannammas newborn son in an orphanage and lies that the child was stillborn. They both decide to leave the place and settle in Bangalore. When Raja returns, he learns that Kannamma had left Kalathur. His inquiries in Sevalpatti lead him to believe that Kannamma had led an immoral life. Griefstricken, he travels from place to place to forget Kannamma and takes to drinking as a last resort. In Bangalore, he encounters Kannamma in a dancers house where she had come to teach the dancers daughter. Her presence in the house and reticence to Raja’s questions strengthens his belief that Kannamma is a woman of ill repute and in disgust, he returns home. Kannamma’s son Selvam grows up into an intelligent boy and is living in the orphanage in Sevalpatti. Murugan visits the orphanage and on meeting Selvam, decides to shift to Sevalpatti to be near him. Kannamma becomes a teacher in Selvam’s school and feels attracted to him. She invites him to stay with her but he refuses as he has to look after Mani, a lame orphan living with him. Raja is invited to Sevalpatti by Singaram, a rich merchant who wants to marry his daughter Maduram to him, to preside over a school function. Raja takes a fascination for Selvam who acts in the school drama. After the drama ends, he encounters Kannamma again and orders the headmistress to dismiss her. Mani is critically ill and Selvam turns to Raja for help. Raja brings a doctor who is unable to save Mani. Raja takes Selvam with him to the palace. On Selvams insistence, he stops drinking and to give him a mother, also decides to marry Maduram. A seriously ill Murugan confesses to Kannamma that her child is not dead and reveals the identity of Selvam. Kannamma tries to contact Selvam but does not find him in the orphanage. The news shocks Murugan and to soothe his nerves, they move down to their village Kalathur. In the local temple, Kannamma meets Selvam and tells him that she is his mother. On learning from him that Raja is bringing him up and is marrying shortly to find him a mother, she asks him not to mention anything about her to Raja. While preparations were going on for the marriage of Raja with Maduram, she comes to know from Selvam that he is the son of Raja. Singaram insists on a written undertaking that the properties of Raja would go to the children of Maduram only. The news of this conflict spreads in the village. On learning this, Murugan rushes to the palace to own the boy but collapses near the palace gate. Kannamma who has followed takes Selvam and tries to move away when she is intercepted by Raja who demands the boy back. Raja refuses to believe that Selvam is Kannammas son and abuses Kannamma for her shameless life. Ramalingam observes that even in such a humiliating situation, Kannamma is silent and does not breathe a word about her promise to him. He is moved and acknowledges her as his daughterinlaw. Selvam is united with his parents, and Rajas marriage with Maduram is cancelled.
