A Light in the Woods (2014)

Brittany is a spoiled teenage-girl who ventures into the woods with her little brother, Ryan, to find her missing iPhone and gets horribly lost. While desperately trying to find their way out, they stumble across a strange mountain woman living in a worn-out trailer. When the woman goes "mental," cages Ryan and tries to skin Brittany to make leather goods out of her, Brittany is faced with the decision of saving herself, or returning to the crazy woman's trailer to save her brother.
