During the reign of the Vijayanagara Empire, Rani Vasam was a long-standing tradition described as a boon for young women. Under this system, breaking news of a palanquin arriving at a family’s doorstep could seal a future for a daughter as the official resident of the royal palace. Large sums in gold and jewellery were offered to parents in exchange for their consent, but once chosen, these women were isolated from contact with men and required permission for visits. Breach of the rule carried a severe penalty, including execution.
Nagaraju N.T. Rama Rao and Malliswari Bhanumathi of Veerapuram are cross-cousins who grew up as close friends, sharing joys and troubles from childhood. The bond between them irks Malliswari’s mother, Nagamma, who views Nagaraju and his family with resentment rooted in class differences. Nagamma’s disapproval is echoed by the village round, as Narappa—Malliswari’s father and village head—stands as a quiet observer, while Hanumanthappa, Malliswari’s uncle, wields influence as a minister in Krishnadevaraya’s court. The young duo’s friendship becomes a point of tension within the family, especially as Nagamma pushes for Malliswari’s future within the palace walls, which would sever their kinship.
One day, a chance visit to a nearby village leads Nagaraju and Malliswari to shelter in a mandapa during a rainstorm. In the same sheltered space, Krishnadevaraya and Allasani Peddana, along with a contingent of soldiers, discover Malliswari’s striking talent as both a singer and dancer. Unaware of each other’s royal identities, Nagaraju and Malliswari exchange thoughts, and Nagaraju seizes the moment to suggest Malliswari be recommended to Krishnadevaraya for the fabled Rani Vasam. Malliswari views this as a prank, while Nagamma presses for her daughter’s removal to the palace, and Narappa quietly hopes for Malliswari’s marriage to Nagaraju.
Driven by a growing sense of duty and aspiration, Nagaraju decides to leave Veerapuram to earn wealth and win Nagamma’s approval for marriage to Malliswari. His path takes him to Vijayanagara, where he trains as a sculptor and eventually finds success. Yet the reunion with Malliswari remains on hold, for Krishnadevaraya and Tirumaladevi appoint Malliswari as the official resident of the palace, granting her the status of Rani Vasam. This turn of events throws Malliswari into a life of opulence and danger, while Nagamma’s cravings for wealth and status push her to increase the pressure on Malliswari. As Malliswari is drawn deeper into palace life, Nagaraju returns, only to be confronted with the consequences of these political moves and the aching ache of separation.
The narrative thickens as Nagamma aggressively pushes Malliswari toward the palace, and Nagaraju, upon discovering what has happened, sinks into depression. Govindamma, Nagaraju’s mother, begins to falter under the weight of his withdrawal into a life of retreat, haunted by memories of Malliswari. A group of sculptors eventually invites Nagaraju to accompany them back to Vijayanagara to construct a special mandapa for dancers, and he agrees. It is there, at last, that he encounters Malliswari again.
However, their romance faces another obstacle: Malliswari’s maid, Jalaja, fears the severe punishment for any breach of the Rani Vasam rules. Jalaja secretly arranges a midnight meeting for the lovers on the banks of the Tungabhadra river, hoping to safeguard them by arranging a private moment away from prying eyes. The lovers’ path once again crosses the center of power when Krishnadevaraya and his ministers attend the newly built dance hall, and they learn that Nagaraju is among the commissioned sculptors.
That night, Malliswari wishes to meet Nagaraju but is delayed because the palace plans a formal performance of Usha Parinayam, with Krishnadevaraya and Tirumaladevi in attendance. Nagaraju, waiting near the Tungabhadra, slips into the palace and is pursued by soldiers, while Malliswari spots him from afar and calls out his name. To save Malliswari from a death sentence under Rani Vasam, Nagaraju pretends not to recognize her, but the pair soon find themselves jailed for violating the palace’s strict rules.
In the tension that follows, Jalaja reveals the lovers’ true story to Tirumaladevi, and she admits that Malliswari once refused any help and chose to face death with Nagaraju rather than bow to the palace’s demands. The next morning, as the nooses are prepared, the lovers confront Krishnadevaraya. A passionate confrontation ensues in which Nagaraju blames the king for orchestrating Malliswari’s forced entry into Rani Vasam, while Krishnadevaraya defends his actions and champions the lovers’ bond. Ultimately, the emperor forgives both Nagaraju and Malliswari, and their union is celebrated in a grand royal ceremony within the palace, marking a hopeful end to a tale woven from tradition, loyalty, and the enduring pull of true love.
