Bhool Bhulaiyaa 2 (2022)

Within a mansion in Bhawanigarh, Rajasthan, in 2004, powerful sorcerers and priests perform sacred rituals, and supernatural events begin occurring throughout the palace due to a malevolent spirit named Manjulika, who is determined to attack the family's daughter-in-law, Anjulika. A sorcerer intervenes and forces the spirit into a chamber, sealing it inside with a powerful trishul and sacred amulets placed on the door. Afterwards, the family abandons the mansion for safety.

Eighteen years later, in Himachal Pradesh, travel vlogger and influencer Ruhaan Randhawa meets medical college student Reet Thakur, who is travelling to Bhawanigarh via Chandigarh to reluctantly marry her fiancé, Sagar. They board a bus to Chandigarh but cut short their journey to attend a music carnival Reet agrees to be in at Ruhaan's suggestion, later discovering that the bus on which they were supposed to travel had met with an accident, killing everyone on board. Subsequently, the Thakurs, owners of the abandoned mansion, presume Reet, the elder daughter of the family, to be dead. Reet attempts to contact her family, but overhears a conversation between her younger sister Trisha and Sagar over the phone, realizing that they are having an affair. Hoping to spare them from a loveless marriage and avoid marrying Sagar herself, Reet goes along with her family's assumption of her death and travels to Bhawanigarh with a hesitant Ruhaan.

Reet drags Ruhaan into the mansion, despite his belief that it is haunted. Together, they hide in the abandoned ancestral mansion, but Chote Pandit, a priest, notices that the mansion doors have been opened and informs the Thakurs. Accompanied by the villagers, they enter the mansion. Reet hides, and they find an exposed Ruhaan, who covers up the situation while by falsely claiming that Reet's spirit led him there and that her final wish is to see her family living in the ancestral mansion, with Trisha getting married. Influenced by Ruhaan, the Thakurs arrange Trisha's wedding to Sagar. Due to his supposed ability to communicate with spirits, Ruhaan becomes popular as Rooh Baba, and he and in-hiding Reet become friends. When Ruhaan is led to the room where the spirit was trapped, Anjulika, Reet's sister-in-law, warns him to stay away from it and reveals that the spirit is actually her twin sister, Manjulika.

A flashback reveals that the sisters had moved to the mansion when their father, Debanshu, was appointed to manage the Thakurs' accounts. Debanshu's preferential treatment towards Anjulika's talents instilled jealousy in Manjulika, which gradually turns into hatred. Both sisters fall in love with Kunwar Thakur, Reet's elder brother. However, Kunwar reciprocates Anjulika's feelings, leaving Manjulika enraged and heartbroken. Seeking solace in learning black magic, Manjulika decides to use it as a weapon against Anjulika. On the night of Kunwar and Anjulika's wedding, Manjulika brutally stabs Debanshu after he discovers the truth and sets out to murder Anjulika. However, Anjulika defends herself and fatally stabs Manjulika in self-defence. Even after death, Manjulika's spirit continues tormenting the family and paralyses Kunwar by pushing him off a balcony. The priests eventually capture Manjulika's spirit and imprison it in a room.

After the flashback, Reet's father reveals to Ruhaan that Manjulika's curse has killed eight members of their family. Chote Pandit's elder brother, Bade Pandit, and his elder brother's wife, Panditayeen's business is suffering because of Ruhaan's popularity. One night, Chote Pandit finds Ruhaan and Reet wandering around the mansion and discovers the truth. With the help of Bade Pandit and Panditayeen, Chote Pandit leads a search of the mansion. Knowing that no one would dare enter Manjulika's room, Reet decides to hide there, and Chote Pandit's accusations are proven false to the family. Once freed, Manjulika attacks Anjulika, who discovers that Reet is alive and joins forces with Ruhaan and Reet to ward off the spirit. They seek help from the same priest who had captured Manjulika's spirit, but he informs them that he requires three days. Manjulika's spirit possesses the priest, forcing him to kill his disciples before he is himself killed. Ruhaan encounters the spirit and falls from a terrace in terror.

Ruhaan returns to the palace, singing and speaking in Bengali, claiming to be Manjulika, revealing that he is possessed. The Thakurs spot Reet and discover that she is alive. Ruhaan attacks Anjulika, who uses Reet as a human shield by threatening to slit her throat if Ruhaan attacks her, while addressing him as "Anjulika", confusing the family. Ruhaan then reveals that he had merely been pretending to be possessed and that the woman who died in 2004 was actually Anjulika, while the woman living with them is the real Manjulika.

In 2004, after killing Debanshu with the assistance of the priest, who is revealed to be Manjulika's accomplice, Manjulika used black magic to manipulate Anjulika and steal her identity. Disguised as Manjulika under the influence of black magic, Anjulika attacked Manjulika, who then stabbed her to death under the guise of self-defence. When Kunwar uncovered the truth, Manjulika pushed him off the balcony, paralysing him and preventing him from exposing her. She also murdered eight members of the family after they learnt the truth. In the present day, Anjulika's spirit attacks Manjulika and imprisons her in the same room in which she had been locked in 2004. Anjulika's spirit shares a final moment with her family and asks Reet's father to forgive her for revealing the truth about Anjulika and Manjulika. She thanks Ruhaan and asks the family to leave, as she has unfinished business with Manjulika. Anjulika enters the room and tortures the real Manjulika to death. The Thakur family departs, and the mansion is abandoned once again.
