Elise and Matt Whittaker have been together for a decade. Elise is doubtful that a spontaneous weekend trip to a secluded cabin will rekindle the lost love in their relationship. Upon arrival, they find a note in the cabin instructing them to keep the fire lit, for when it goes out and the cold seeps in, so too do the spirits of the woods. After a creepy figure begins to plague her at the cabin, Matt is insensitive to Elise’s fears, chalking the incidents up to teenage pranks. When the fire goes out, will Elise be able to save herself? Or will she and her marriage die along with the flames?
