Wisp (2013)

What begins as a school project has dire consequences. Four college students venture deep into the woods as they pursue the legend of Will-O-Wisps, ghostly lights that lead unwary travelers to their doom. When contact with the outside world is severed, tensions rise, putting a major strain on the social fabric of the team. Unable to eat and unable to sleep out of fear of an unknown biological threat, they realize they must band together if they are to have any chance of survival. WISP is a cautionary tale, a reminder that some legends are better left in the past. These young students pay the ultimate price for uncovering the long-kept secret of these mysterious lights.
