The film is a Bollywood's mix from three Hollywood's classic films of horror: The Shining (1980), The Entity (1982) and Poltergeist (1982). The first one by a haunted house in the middle of the mountain, the second one by a ghost stalker that sexually disturbs to a woman and the third one by an evil spirit that it's in a communal grave close to the house.

The car Sanjana (Tabu) drives in the movie is a red 1995 MARUTI Udyog Esteem.
Tabu's only horror film.
The film did not have any hero.
