What Happens in Aval Oru Thodar Kathai: Full Plot Summary

The whole story of Aval Oru Thodar Kathai (1974) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

Kavitha is the sole breadwinner of her family, which includes her mother, widowed sister Bharathi, an unmarried younger sister, a blind younger brother, a drunkard elder brother Murthy, his wife and children. Her father had abandoned the family and become a sadhu. Conscious of her responsibilities, Tilak, her long-time boyfriend, patiently waits for Kavitha, and when he meets Bharathi, he pities her and slowly becomes passionate about her. On learning this, Kavitha sacrifices her love and gets them married. Murthy changes his wayward behaviour, becomes responsible and works as a bearer at a restaurant. An impressed Kavitha accepts him as the head of the family. Kavitha's boss Arun Ghosh offers to marry her, but Kavitha does not give a positive reply.

Chandra, Kavitha's friend, dates Chandrasekhar, a womaniser and Kavitha's colleague, despite her warnings. Earlier, when Chandrasekhar had written a love letter to Kavitha, she complained about it to her boss, who reprimanded Chandrasekhar. Hence, Kavitha does not approve of Chandra's relationship with him. A lustful Chandrasekhar also dates Chandra's widowed mother; on learning this, Chandra attempts suicide. Kavitha and her co-tenant Gopal save Chandra and advise her to marry Gopal. In turn, Chandra advises Kavitha to marry Ghosh. Kavitha accepts the marriage proposal as she now feels confident about Murthy taking care of the family.

On the day of the wedding, Murthy's wife asks him to get back the silver lamp pledged by him earlier, to be gifted to Kavitha for her wedding. While returning to the wedding hall, he seeks a lift from Chandrasekhar, not knowing him. Murthy realises that Chandrasekhar is actually coming to stop the marriage of Kavitha and Chandra when Chandrasekhar states that he had affairs with both of them. Murthy pleads with him not to come to the marriage hall and create any confusion, but Chandrasekhar refuses. A scuffle ensues in which Murthy is killed by Chandrasekhar using the lamp before the police arrest Chandrasekhar. When the marriage is about to take place, Kavitha learns of her brother's death from the police. She then convinces Ghosh to accept her younger sister as the bride as she needs to support her family again. At the same time, Chandra marries Gopal. Kavitha returns to taking care of her family like before.
