The film stars Radhika Kumaraswamy, Bhanupriya, and Rishi, while Satya Prakash, Prudhvi Raj, and Annapoorna play supporting roles.
The story revolves around Rajeshwari (Radhika Kumaraswamy), a girl born under the Simha Rashi zodiac sign who has divine faith in Goddess Akkamma (Bhanupriya).
The backstory of the film shows that to protect the world, Akkamma must herself go under the arrest of a supernatural element, which can only be uplifted when a person born under the Simha Rashi zodiac sign sacrifices herself in fire.
In the process, Rajeshwari marries Prasad (Rishi), the heir of a wealthy family who treats him badly and drugs him to make him mentally unstable in order to capture his wealth.
However, Prasad's family members, in the influence of Karkotakudu, remove the kumkuma and mangalsutra away from Rajeshwari and make her wear white clothes.
In order to symbolize Rajeshwari back as a married woman, other goddesses donate materials like kumkuma, mangalsutra, red sari, jasmine flowers, rings, kohl, toe rings, necklaces, and bangles, which will symbolize Rajeshwari back as a married woman.
With Akkamma's blessings and parabrahma, a divine energy is formed inside the fire, and Rajeshwari transforms into Goddess Narasimhi (female shakti of Narasimha) .She kills Karkotakudu with her mega divine superpowers, and everything finally becomes back to normal, with Rajeshwari returning to normal human form.
