Nikita Roy

Nikita Roy is a celebrated author and rationalist based in London. She is a member of the International Rationalist Committee (IRC) and specializes in debunking myths, superstitions, and "godmen." Her brother, Sanal Roy, is her mentor and a fellow rationalist who is investigating a powerful spiritual guru named Amar Dev.

Sanal goes missing while investigating Amar Dev’s cult, the "Tru Faith Foundation." He is eventually found dead, and the police rule it a suicide. Nikita refuses to believe her brother—a man of logic and science—would kill himself. She is convinced Amar Dev murdered him to protect his secrets.

Nikita arrives in London to take over Sanal’s investigation. She is aided by Jolly , her ex-boyfriend and fellow investigator. Amar Dev is a calm, menacing figure who claims to heal people by absorbing their "darkness." When Nikita confronts him, he issues a challenge: If she can prove he is a fraud within a specific timeframe (often cited as a few days/a week), he will surrender. If not, she will face the consequences of her skepticism. As Nikita digs deeper, her reliance on logic begins to crumble. She starts experiencing unexplainable, paranormal events—visions of her brother, eerie noises, and shadowy figures. She tracks down an informant named Freya, who was a mole inside the cult, but Freya commits suicide in a gruesome manner right in front of them, seemingly driven mad by a "curse."

In the finale, Nikita confronts Amar Dev at his ashram. The film reveals that Sanal didn't just die; he was psychologically broken by Amar Dev’s methods. Nikita finds herself falling into the same "trap" as her brother, a mix of hallucinations and reality distortion engineered by the cult. Nikita sought to expose the "Book of Darkness" (the metaphorical or literal secrets of the cult), the darkness (fear and irrationality) consumed her just as it did her brother. The film closes with the unsettling idea that faith—or the manipulation of it—can be more powerful than logic.
