The film begins with Saint Rakthabhisha & Sriganda, king of Kanchipuram, as disciples of Narada. The two develop a rivalry, feeling superior to the other. Rakthabhisha is a great devotee of Goddess Lalitha; he contracts an underground temple and performs penance and boons for salvation. The goddess proclaims he acquires only after the marital life and blessing with a son. Then she bestows him a ring as a lock to the temple, which is inaccessible even to him without it. After that, Rakthabhisha lands Chandrapuri with his acolyte Krishna, a freak. Mandaka, a gallant, the son of Nityananda, a colleague of Rakthabhisha, visits for his blessings. Parallelly, Karunakara, the king of Chandrapuri, arrives with his blind daughter Rajyalakshmi & lame niece Kumari. Sriganda also reaches therein and challenges Rakthabhisha to create heaven, and he does so by transforming Mandaka into Indra, Rajyalakshmi & Kumari into Apsara. Forthwith, Sriganda disappears, but he cannot remove the woman's beauty. Here, Sriganda is attracted to Rajyalakshmi and attempts to abduct her when Prince Ravi Chandra secures her with Mandaka. Karunakara gives hospitality to two and adopts Mandaka. Plus, Ravi Chandra & Mandaka turn into besties. Meanwhile, Mandaka & Kumari, Ravi Chandra & Rajyalakshmi crush.

Eventually, Sriganda sends the proposal to knit Rajyalakshmi when Mandaka, with wit, performs the nuptial of Ravi Chandra & Rajyalakshmi. Chandramma, the sister of Karunakara, quits to Kanchipuram with her daughter Kumari, intending to wedlock her with Sriganda. Mandaka gets here in disguise and continues his love affair with Kumari. After a while, Rajyalakshmi conceives, and Ravi Chandra proceeds to his hometown. Consequently, Sriganda conquers Chandrapuri and captures Karunakara, but Rajyalakshmi escapes. Being conscious of it, Mandaka attempts to free Karunakara and is chased by the soldiers. Besides, Rakthabhisha loses the ring that Mandaka obtains and enters the secret temple. Eventually, he makes Krishna normal, via whom Mandaka is startled to know that Ravi Chandra is the transformation of Rakthabhisha to attain his salvation. As of today, Mandaka affirms that this injustice should not be allowed. Parallelly, they detect Rajyalakshmi, who gives birth to a baby boy, and Mandaka goes on for Rakthabhisha, leaving the two under Krishna's guardianship. Here, Mandaka acquires the boon for the goddess by installing the ring at the feet and constantly shifts Rakthabhisha into Ravi Chandra. Eventually, Sriganda plans to crown his lieutenant Virupaksha as king of Chandrapuri and splice with Kumari. Amid, they find Rajyalakshmi and seize her. Krishna reveals it to Mandaka & Ravi Chandra, and there are two strikes where Sriganda is defeated and loses his powers. At last, Karunakara is re-crowned, and Rajyalakshmi is united with Ravi Chandra. Finally, the movie ends on a happy note with the marriage of Mandaka & Kumari.
