Gundamma is a rich widow who ill-treats her stepdaughter Lakshmi, a selfless person who is reduced to working as a maid. Gundamma has a daughter Saroja and a son Prabhakar. Prabhakar is in love with Saroja's friend Padma. Gundamma has a half-brother Ghantaiah, a cunning but weak milk vendor. Ghantaiah wants Gundamma to marry off Saroja to his criminal son Bhoopati, who is in prison. To achieve this goal without the knowledge of Gundamma, he spoils every marriage proposal Saroja receives. Saroja's arrogance and Lakshmi's courteous attitude indirectly help Ghantaiah. Gundamma decides to marry off Lakshmi to a vagabond and Saroja to the son of Ramabhadraiah, a wealthy man living in a faraway town.
