A series of child abductions and murders has left the Mumbai Police perplexed and unable to solve the case. Consequently, the case is handed over to the CBI, who assign trainee Reet Oberoi to crack it. As she investigates, the evidence points towards Lajja Shankar Pandey, a religious fanatic who believes in sacrificing children to gain immortality. Pandey's erratic behaviour and Reet's own traumas — witnessing her older brother Jassi, a terrorist, being gunned down by the police in their home — compel Reet to seek help from a prisoner unjustly implicated, the genius Professor Aman Verma.Initially, Aman is rude and unwilling to assist Reet, but she eventually persuades him to help. The case becomes more challenging when Reet learns that Pandey has kidnapped the Home Minister's only child. Overwhelmed by the pressure, her childhood traumas, and phobias, Reet faces opposition from the local police, partly due to Verma's unconventional methods. As they spend more time together, he helps her conquer her fears, and they both fall in love.Ultimately, they track down Pandey, who plans to perform his final sacrifice during a solar eclipse (Soorya Grahan), believing it will grant him immortality. Aman and Reet manage to rescue the child and kill Pandey. However, during the confrontation, Aman sustains fatal injuries. In his final moments, Aman and Reet share a kiss before he dies in her arms. Reet receives a hero's welcome and discovers a renewed sense of purpose within herself.
