Delhi-based Rehan is instructed by his Realtor father to travel to Koti, near Shimla, and make preparations to sell Billimoria-owned 'Glen Manor' to the Mittal family for Rs.200 Crores. Upon arrival, he disregards warnings from local residents that the mansion is haunted by 'Shaitan'. Shortly thereafter he hears screams and inexplicable movement within the mansion. He then finds out that there are two entities that have persisted in this mansion for 80 years. Rehan will soon find himself transported back to August 17, 1936, where he hopes to change the past.
