Once upon a time, there was a kingdom; its King Mahavira announced Swayamvaram, i.e. one's choice of selecting a bride for his son, Prince Raja Sekhara, without his wish. Princesses of various kingdoms arrive for the ceremony, where Raja Sekhara makes 3 conditions for them. The bride should build a diamond palace for him without the help of her parents or in-laws; she should become pregnant with him without his knowledge, and she should allow him to marry the girl he loves. Princess Manohari agrees to it and knits him. Soon after, Raja Sekhara reaches Pakshirajyam with his friend Ammanna, where he falls in love with Pakshiraja's daughter Komali and her association. He forgets Manohari. On the other side, to keep her promise, Manohari performs the dance programs to build the diamond palace. Meanwhile, she finds the whereabouts of Raja Sekhara and immediately reaches Pakshirajyam along with her friend Rani, where its commander in chief Dandayya, mistakes Rani for the Queen and Manohari as the maid. As Dandayya is attracted to Rani, he requests Manohari to make acquaintance with the Queen. Manohari makes a condition to build a diamond Palace for her, and he does so.
At the same time, Pakshiraja suffers from an ulcer on his back, which does not heal from any treatment, so he announces that whoever gets medicine for it will make his daughter's marriage with him. On that night, Manohari and Rani, in disguise as men, see Raja Sekhara and Komali in the garden when they come to know about the illness of the King and also listen to the remedy for it through bird speakers. After facing many troubles, they achieve the medicine, cure the King's disease and take Komali away. Knowing this, Raja Sekhara faints when Rani takes him to their place; in the darkness, he mistakes Manohari for Komali and sexually interacts with her. The next day morning, Manohari leaves that place and goes back to her in-law's house. Meanwhile, Dandayya silently observes the movement of Raja Sekhara and Komali and captures them. He keeps Raja Sekhara in prison and forces Komali to marry him by keeping her in a cave. Eventually, Ammanna releases Raja Sekhara, and they return to their kingdom. Rani follows Dandayya, and with the help of Pakshiraja, she protects Komali and gets Dandayya arrested. By the time Raja Sekhara reaches their kingdom, Manohari gives birth to a baby boy. Seeing it, Raja Sekhara becomes furious and orders his men to burn her. The rest of the story is about how Manohari proves her purity.
