A sentimental love triangle focussing on Suguna (Savitri), adopted by Rao Bahadur Venkatramaiah and his wife Kanakadurga, who is ill-treated when the couple have a child of their own. She is given away to a clerk, Vengalappa, who educates her and makes her a doctor. She falls for the poet Chandram (ANR), but he insists that she marry the terminally ill Raghu, who loves her too. Chandram now marries Valarakshmi (Girija), the daughter of Venkatramaiah. Varalakshmi, however, suspects that Chandram still loves Suguna. The film was a major 60s hit, mainly for its lyrics and music.
