The old palace is inherited by Siddharth, who lives in America. He decides to return to his hometown to live and work in India. The whole family is looking forward to his return, particularly Radha, as she is destined to marry Siddharth. Unfortunately, Siddharth returns home along with his beautiful wife Avni. Radha's heart is broken. For Siddharth, it was a long and tiring journey. Still, it is nothing compared to the labyrinth he has to unravel. Avni is warned of a ghost's "bad neighborhood" in forbidden rooms. No doors can be opened. Though, female curiosity knows no limits. The locks are removed, the doors are opened and the ghost is released. Is this a phantom or someone's joke? To sort things out, family moves into the palace. Now they are closer to a married couple. Seeking to protect the mansion from negative influence, family decides to contact a priest. By mischance, a chaplain is away on a trip. Then, Siddharth calls his American friend and psychotherapist Aditya ...
The palace is like a maze. It features a number of rooms, passes and secrets. The main secret is a ghost. Fearing of the mystery, all tend to stay away from it. Siddharth's uncle, Badri Narayan, says the mansion holds a long secret, while contact with it can be deadly.
Being quite rational, Siddharth pays no attention to his family warnings. He agrees to live here. Soon, this decision seems rather hasty. Who would have thought: a calm rationalist that came from prosperous America to the ancestral land gets into a confused and even mystical story?
First, Siddharth is inclined to blame Radha. He believes she is mad to take vengeance on for his wedding to Avni. Further, his guesses turn wrong. Once in the night, he meets a phantom of Manjulika. The ghost promises to return and avenge on a day of Durgashtami.
What to do: trust own feelings or eyes? Being a subject of quiet pride, royal origin brings him the biggest headache. Avni is an every man's dream. She combines both simplicity and beauty. With her, one feels easy and comfortable. Avni is a Siddharth's wife. She is proud of it. Side by side, she goes with her husband, in good and bad times. But this time, something goes beyond understanding.
There goes an engagement of Nandini, Siddharth's cousin, and Sharad Pradhan. After finding Anvi fighting Sharad, Siddharth learns she suffers from a multiple personality disease. She imagines herself as someone else. Aditya reveals it is Avni that hides the phantom inside of her. As a proof, he provides the results of his investigation: visiting Avni's hometown, Dr. found strange facts about her child years. To convince Siddharth of his wife's madness, Aditya asks him to provoke Avni for unconscious acts. In a fit of deliriousness, Avni imagines herself as a Manjulika, which is a Bengali classical dancer. She tries to kill Siddharth, just like Manjulika killed the king Vibhuti Narayan for murdering her lover Shashidhar. Loving his wife, Siddharth wants Aditya to cure her.
Dr. Aditya Srivastava is a discreet, practical and serious man. Are these signs of a real doctor? None of them suits Aditya Srivastava! Radical, eccentric, unpredictable. None of these definitions can be attributed to a doctor ... and all this exactly characterizes Dr. Aditya! No wonder, he finds himself in a situation no one ever faced. His brilliant mind finds an unexpected solution. Appealing to Manjulika, Aditya asks her to set Avni's soul free. In her turn, she wants to kill the king and accomplish the act of revenge. This time, the priest finally visits the mansion. Together with Aditya, they succeed to deceive the phantom. Manjulika is satisfied with the “revenge” and disappears. Now, Avni is cured. Radha and Aditya feel affection for each other. Aditya proposes a girl, while she is really happy.
