Ramu Shastrigal is a poor Brahmin living with his wife Visalam and their eight children. His rigid principles and obstinate behaviour become obstacles to his family's progress. His spendthrift sister Janaki lands in his house with her daughter, adding to their woes and penury. Lalitha, the eldest daughter of Ramu Shastrigal, is enthusiastic to work but her father does not permit it. She bonds with the family's neighbour Nadesa Udaiyaar and his son Thangavelu. Thangavelu sympathises with Lalitha's condition and fondly presents a saree to her, which she accepts. However, Ramu Shastrigal insists that it should be thrown out and complains about this to Udaiyaar, who then berates Thangavelu for his act. Thangavelu expresses his love for Lalitha and his desire to marry her; when Udaiyaar refuses to permit it, he leaves the house. Thangavelu's sudden exit depresses Lalitha.
