One mistake, one road, one night, leaves her with a disturbing encounter and the paranoia that follows haunts her for days. Ivy just wanted to get home from a fun day with her friends, when her car runs out of gas and leaves her stranded on the side of a mountain road with only an S.O.S signal on her phone. While waiting for the police to help her out, she encounters something strange...something terrifying. And it follows her, even when she thought she got away.
