My Changed Concept

I have decided to change my concept as it was too similar to the trailer of 'Quarantine' however I will still use the final shot when she gets dragged along the floor. My idea is a couple are out hiking and it begins to rain, they look for shelter in barn. Man goes off to search for help and a phone. The barn has no light and she only has one torch. As she stays in there, the rain isn't dying down. They here a bang, they find some newspapers from years ago, and recent ones that have been circled and drawn over.  The woman wants to leave she can't, in background there is a possessed woman.  The phone rings, with no answer. finds a voodoo dolls of her, screams, then dragged along the floor in the same shot as the quarantines.
