During a family picnic at Fatehpur Sikri, an old man warns that every stone in the fort is steeped in a story written with blood, and that only by seeking out the red stone, Lal Patthar, will they glimpse the fort’s dark past. The family laughs it off, but the old man’s paranoid eyes flicker with warnings—he even says blood can be seen in a glass of plain water. As he speaks, he unravels the saga of Rai Nagar, a lineage haunted by a centuries-old curse.
Raja Raghav Shankar Rai, the kingdom’s first ruler, is introduced as a bandit who commits a brutal act against a peasant woman named Sonmai and takes her as his wife. Sonmai’s fate, after this violence, is to unleash a curse that dooms the entire family to insanity. In the long arc of generations, the tale narrows to Gyan Shankar, the lone male heir in the seventh generation, while his grandfather Raja Ram Shankar Rai is described as mentally unstable. As a boy, Gyan intervenes when his drunken father Anand Shankar attempts to assault a maid, and the boy is sent away to Allahabad, where he studies history and psychology before returning home with Chhotu, his trusted servant.
To claim the throne, Gyan contemplates marriage, yet he fears that marriage could unravel the life of any woman under Sonmai’s curse. The story then shifts to the hunt in the jungle, where Gyan—Raaj Kumar—goes in search of a man-eating tiger. After the kill, he helps fend off a band of attackers who are fleeing with a palanquin. In the aftermath, he discovers a woman named Saudamani, the widow of Gokul, concealed inside the palanquin. Saudamani, who would later be known as Madhuri, becomes entangled with Gyan: he brings her back to the palace and, drawn to her beauty, treats her with a mixture of care and domination. Saudamani is introduced to the court as a lower-class woman who gradually gains influence in the grand house, while Gyan’s initial fascination gives way to a complicated dynamic where he tries to educate and shape her, only to realize she possesses a stubborn, practical outlook that cannot be “taught” in the traditional sense.
Ten years pass, and Gyan leaves behind the palace life. He encounters a younger woman named Sumita, Rakhee Gulzar, at a singing event. Sumita’s father Harishchandra Chakraborty is a gambler in heavy debt, and he arranges a marriage between Sumita and Gyan to secure money. Sumita arrives in India from London, accompanied by her mother Madhu, Dulari, who is strongly opposed to the union. Sumita’s former life includes a childhood sweetheart, Shekhar, Vinod Mehra, who taught her music. Madhuri, still a powerful presence in the palace, grows jealous and begins to sow doubt about Sumita’s intentions, insinuating that Sumita and Shekhar were once close.
Gyan attempts to balance both Sumita and Madhuri, often leaving them disappointed. He senses Madhuri’s jealousy when she appears to suspect Sumita of infidelity with Shekhar, and the tension boils over when Madhuri manipulates a situation by guiding Shekhar to Sumita’s room under Gyan’s supposed orders. In response, Gyan confronts Madhuri’s mounting jealousy, ultimately driving her away from the palace after a brutal exchange in which he scars her face.
Seeking a fresh start, Gyan escorts Sumita to Agra, where Sumita visits the grave of Maulana Salim Chisti, hoping for a child. Gyan, convinced that Sumita and Shekhar still share a bond, writes to Shekhar and asks him to come to Agra. When Shekhar arrives, Gyan feigns illness and sends them to view the Taj Mahal, then follows. He catches only fragments of their conversation and becomes convinced that Sumita and Shekhar remain connected in their feelings.
On a full moon night, Gyan invites Shekhar to explore Fatehpur Sikri’s fort and stage a supernatural encounter to confirm his suspicions. He uses blanks to threaten a ghostly figure, then replaces them with real bullets, turning the act into a deadly confrontation. Sumita, who had been invited as part of the ruse, becomes the target and dies. In the chaos, Gyan shoots Shekhar, and his rival dies as the curse of Sonmai seems to be fulfilled. Gyan is left wandering the fort, waiting for Sumita’s ghost to appear on every full moon night.
Yet the twist reveals that Madhuri—alive all along—has been living under an assumed role, quietly playing Sumita’s part to provide solace to Gyan. The legend of Rai Nagar ends with a haunting sense that the past’s blood-soaked tales continue to echo through the stones of Fatehpur Sikri.
