The trailer ends with this clip, which does bear resemblance to a clip form 'The Conjuring', but the story seems to be a little different than the usual horror movies.
The lead pair Bipasha Basu and Karan Singh Grover, in the trailer, look like a smart, city couple.
Popular actress Sulbha Arya also has a crucial role to play in the movie. She plays an old women who warns the protagonists of a horrific incident before they get into trouble with the evil spirit.
The major part of the film is shot in a house in the beautiful backwaters.
Bipasha Basu took to Twitter to describe the film. A love story with chills, my new film is tentatively called 'Alone' co-starring Karan Singh Grover," she had tweeted.
'Alone' has been produced under the banner of Panorama Studios. The Bhushan Patel-directorial is the Bollywood remake of the Thai horror film 'Alone'.
The trailer starts with a picture of conjoined twins in a crib.
Going by the first promo of 'Alone', a story of conjoined twins, the film promises to entertain and scare its audiences.
The much-awaited horror film also features sultry love scenes and love songs.
The cinematography of the film looks interesting. The camera movement induces doubt and fear in the mind of the viewers.
The promo also has clips of Bipasha Basu (who plays a double role) playing with her twin sister. The two sisters are shown to be very close.
