Another Thanksgiving holiday is coming, and the once bustling university campus suddenly becomes empty. However, in the empty campus, a slightly lonely and boring figure lingers. Her name is Justine (played by haley bennett in Harry Bennett), and she is forced to stay at school because of the high air ticket price, school and subsidies. Not long ago, she bid farewell to her beloved boyfriend, and even her dormitory friend who had promised to accompany her temporarily ran home for the New Year. Justine bored away a long time, but she didn't expect danger to approach her. Recently, Justin's city lost a female college student who was addicted to parties. Outside, Justin drives to a nearby supermarket to shop, but unexpectedly, she meets an unfriendly woman (played by ashley greene ashley greene).
