Bhool Bhulaiyaa

Badrinarayan "Badri" Chaturvedi (Manoj Joshi) heads a Brahmin family whose ancestral palace in Rajasthan is believed to be haunted by the ghost of Manjulika, a classical dancer from Bengal. Siddharth Narayan Chaturvedi (Shiney Ahuja) and his archeologist wife Avni Chaturvedi (Vidya Balan), the son and daughter-in-law of Badri's elder brother return to their native village from the United States and decide to stay in their ancestral palace. This leads to Siddharth's childhood love interest Radha (Ameesha Patel), who is Badri's adopted daughter, feeling heartbroken but she immediately recovers. Siddharth is crowned as the king, his right to the throne.

The palace where Siddharth were staying was once occupied by Raja Vibhuti Narayan, Siddharth's ancestor. According to legend, he had developed an infatuation for Manjulika, a beauty hailing from Bengal and an exceptional dancer in his court, who in turn was in love with Shashidhar, another dancer, who resided in a house just behind the palace and often met her secretly. On the night of Durgashtami, when the king got to know of their affair and their plan to elope, he called them to perform a dance one last time in the court. When Shashidhar bowed in the end, the king beheaded him and imprisoned Manjulika in her room. On the day of the king's marriage, Manjulika hanged herself and swore that her spirit would not allow any king to live in that palace. Various omens started taking place after that, presuming that the evil eye may have befallen the kingdom. Vibhuti Narayan too died soon afterwards under unknown circumstances. Soon, with the aid of powerful sorcerers, both Shashidhar's and Manjulika's spirits were locked up in a room on the third floor of the palace using a sacred talisman.

Avni falls in love with the palace and learns about Manjulika and her tragic story. Events take a twist when Avni, keenly interested in the story and the treasure and jewelry allegedly hidden in that room, obtains a copy of the third-floor room key and opens the forbidden locked room that supposedly contains the ghost of Manjulika. Unnatural events once again start taking place inside the palace. Murari (Asrani) and Batuk Shankar (Paresh Rawal) try to ward off the evil eye with the help of a priest, Shri Yagyaprakashji Bharti (Vikram Gokhale), but unfortunately the priest has gone to London and is unsure when he might return.

Siddharth starts suspecting Radha for all the strange occurrences. He thinks she has gone crazy since he was supposed to marry her but married Avni instead. He calls his friend, psychiatrist Dr. Aditya Shrivastava (Akshay Kumar) from New York, to try to figure out what the problem is with Radha. Once Aditya reaches the palace, things become comical, as everyone thinks he is a fool, though he is very intelligent and a successful doctor. Eventually, Aditya falls in love with Radha. One night, Aditya hears Manjulika's ghungroo and the sounds of her Bengali song coming from the third floor. He goes and knocks at the door, but sees no one. Next morning, he asks Avni to take him to the third floor. She shows him the place, even Manjulika's room, and her belongings. Aditya studies the matter closely and prepares for the night. That night he encounters Manjulika, and talks to her behind a locked door, pretending to be the cruel Raja, and dares her to strike. The ghost angrily vows to take her revenge on the auspicious day of Durgashtami.

During the engagement of Siddharth's cousin Nandini to one Sharad Pradhan (Vineeth), Avni accidentally spills Haldi on Sharad and takes him away to get him cleaned. When Aditya and Siddharth search for her, they see that there is a struggle between Avni and Sharad, and quickly intervene. Siddharth thinks that Sharad was assaulting Avni, but Aditya tells him that Avni is the real culprit, not Radha as previously suspected. It is revealed that Avni has dissociative identity disorder, a mental disorder that affects the person's identity, making them think they are someone else. Sometimes, Avni tends to forget her own self and becomes Manjulika. Aditya explains that Avni has been responsible for all the strange events happening around the palace. He reveals that he visited Avni's hometown to gather information about her childhood and has factual evidence. He informs them that she believes Siddharth is the evil king whom she wants to kill and Sharad is her beloved Shashidhar because he currently resides in the same house that Shashidhar used to live in.

He tells a half-convinced Siddharth to provoke Avni by refusing her from going out. As he does, soon Avni loses her temper and shows him the dark personality of Manjulika. But she returns to normal quickly, much to her husband's shock and dismay. Later, Siddharth begs Aditya to cure Avni.

During Durgashtami, Aditya and Siddharth along with Sharad see Avni assume Manjulika's identity, dressed as her and dancing to the tunes Manjulika had been dancing to with Shashidhar before the king murdered him. The tragic love triangle of the old king Vibhuti Narayan who wanted Manjulika for himself, and Manjulika and Shashidhar's love story is revealed. Avni imagines herself as Manjulika and Sharad as Shashidhar, dancing in the court of the king. Avni completely assumes the identity of Manjulika and tries to kill her own husband Siddharth; she sees him as the king who had killed Manjulika's lover.

Seeking to cure Avni, Aditya triggers Manjulika's personality and makes her promise to leave Avni if she gets the opportunity to kill the king and take her revenge. The priest Shri Yagyaprakashji Bharti arrives and with his help, during the ritual of Durgashtami, Aditya lays out an intricate plan to trick Manjulika into thinking she is killing the king (Siddharth) when she is actually slaying a dummy. After the orchestrated murder, Manjulika, now content, leaves Avni forever. Avni is rid of dissociative identity disorder and everything ends well. The family members, now very pleased with Aditya, thank him for all his help, saving two lives.

Aditya tells Radha, to whom he has taken a liking , that he will send his parents over if she is interested in marrying him, to which a happy Radha gives her silent consent.
