Whether the events were the product of a massive human plot or something truly supernatural is something many viewers are still trying to figure out after the film's climax.
The story follows Sinha's character, Nikita Roy, who is an author and an IRC member. When her brother, Dr Sanal Roy, played by Arjun Rampal, mysteriously passes away in London, her world is thrown into chaos. Although the police claim it was a suicide, Nikita suspects foul play. Sanal was about to expose the charismatic spiritual leader Amardev (Rawal), whom she suspected of exploiting the weak.
Similar to her brother's final days, Nikita embarks on an investigation alongside her friend Jolly (Suhail Nayyar). Still, her tireless commitment to reason is tested when she becomes more immersed in Amardev's cult and starts to encounter disturbing hallucinations, strange noises, and threats from the otherworldly.
Nikita's discovery that her brother's "paranormal" experiences were more than just hallucinations propels the film to its climax. It turns out that Amardev uses a complex combination of pharmacological induction and psychological manipulation.
Like the "supernatural" events that pushed Sanal over the brink, the "supernatural" events that Nikita encounters were partially caused by highly potent hallucinogenic chemicals that were secretly given to certain individuals. By persuading rationalists to perceive phenomena beyond scientific explanation, Amardev aimed to demonstrate his spiritual supremacy and silence his critics.
Nevertheless, the climax introduces an element of uncertainty that departs from the conventional "con man" reveal. During the last showdown, Nikita becomes entangled in a cycle of nightmares that seem too real to be hallucinations. The film implies that Amardev may be using chemistry and technology to influence his followers, but he may also be drawing on a more sinister, real occult force that he isn't completely in charge of.
Nikita Roy climaxes with a bittersweet victory. She is able to deduce the criminal scheme behind Amardev's business. The proof of the deception and the psychological abuse that Amardev subjected Sanal and others to is captured by Jolly, thanks to her tech-savvy intervention and her personal resiliency.
However, the film's closing shots unveil a haunting trauma. A final "glitch" in Nikita's reality occurs as she leaves the cult's collapse; she has a terrifying vision that echoes her brother's death moments.
The "Godman" is shown to be a manipulator who conjured "miracles" and "curses" through the use of medicines and psychological triggers. Thematically, the film allows room for interpretation. It suggests that, although the man was deceitful, the evil he allowed into the world could have been genuine. Even though she is still alive, Nikita's faith in a material world is no longer solid.
Critics have praised the film for taking a "Western" approach to Hindi horror by focusing on atmospheric and clinical tension rather than standard jump scares. Although the climax was "rushed" by some critics, the uncertainty only serves to underscore the film's main point, which is the dreadful void that exists when reason fails to account for one's own perceptions.
Q: Is the ending of Nikita Roy supernatural or a conspiracy?
A: The ending of Nikita Roy suggests it is both. While Nikita successfully exposes Amardev (Paresh Rawal) as a fraud who uses hallucinogenic drugs and psychological manipulation to create "miracles," the final scene shows Nikita experiencing a "glitch" in reality.
Q: Who is the killer in Nikita Roy?
A: There is no traditional "slasher" killer in Nikita Roy. The antagonist is Amardev, the spiritual leader of the Tru Faith Foundation. He didn't physically kill Sanal but used psychological torture and chemical induction to drive him to the point of a mental breakdown and eventual death, which the police originally ruled a suicide.
Q: What is the Book of Darkness in Nikita Roy?
A: Though the film was originally titled Nikita Roy and The Book of Darkness, the "book" is largely symbolic. It represents the hidden, darker side of human belief and the "unwritten" secrets of the occult that Amardev uses to manipulate his followers.
