Arunagiri (T. M. Soundararajan) was born in the town of Thiruvannamalai in Tami Nadu. Arunagiri was attracted to the pleasures of the flesh and spent his youth in pursuing a life of debauchery. He frequently visited the devadasi Maragatham (C. Lakshmi Rajyam). His sister Aadhi Lakshmi (B. S. Saroja) tries to reform her brother, Arunagiri, so she arranged his marriage with Gnana Valli (Sharadha). And Arunagiri was feeling unhappy in his married life. He neglects his wife and continues in his bad ways. He persuades his sister to sell all their property and their house to get money for his dissipation. He reduces himself, his wife and sister to dire poverty. His sister gave him what ever money she earned herself, to make her brother happy. It was said that since he was used to enjoying his life in debauchery, he started to suffer from leprosy and people were avoiding him. There came a time when his sister had no money to meet his demands for his dissipated life.
