Once upon a time, a kingdom called Simhala was ruled by Rajasimha, who dotes on her only daughter, Kalavati. In her infant, Markandeya Maharshi blesses & bestows a holy thread, Raksha Rekha, to shield her. Kalavati is currently opposed to wedlock, which perturbs her father. Besides, Sudhakar Avanti's prince also so was. So, vexed King Parthapa cages him at a dilapidated house in the forest with his acolyte Dooradarsi. At one time, angels led by Chitra visited the nearby Vishnu temple and were spotted & mesmerized by the handsome sleeping prince. Ergo, they lift him with a cot and shift to Kalavati's palace. In a trance, they exchange rings and nuptials the following day. Forthwith, tragically, Sudhakara is abducted by Chitra, transforming into a garland since she entices him. As of now, Kalavati pledges to retrieve her husband and walks up in men's guise. Midway, she is acquainted with Princess Chandrika, who crushes and knits her misinterpreting as a man. Later, she discerns the actuality and vows to aid her. Besides, Chitra arduously attempts to lure Sudhakara but in vain. Enraged and thwarted, she swears to Sudhakara as a statue and throws him to Chandrika's palace. Being conscious of it, Kalavati seeks to back Sudhakara with her adoration. At last, crestfallen Kalavati casts off the Raksha Rekha when Markandeya Maharshi appears, recoups Sudhakara and curses Chitra to be a vampire. Finally, the movie ends happily with the couple's reunion.
