Saritha (Jayaprada) is a working woman in a middle class family. She works hard to support her widowed sister, unmarried sister, her blind younger brother, her mother, her drunkard brother Murthy Rajnikanth and his family. Her father abandons the family and becomes a saint. Her brother not only does not take responsibilities, but also creates additional problems for her.
She has a longtime boyfriend, who wants to marry her, but she doesn't because of her commitment to her family. His eyes now wander to Saritha's widowed younger sister (Sripriya) who reciprocates his feelings. Saritha, after reading her boyfriend's love letter to her sister, arranges for them to get married, thus giving up her chance of having a life with him. She eventually accepts a marriage proposal of her boss (Kamal Hassan), when she realizes that her brother has become responsible enough to take care of her family. She also helps her distressed friend, played by Phataphat Jayalaksmi to settle in life. She decides to resign from hard work, but could not as the result of turning point in a typical Balachandar style climax.
