On this specific Friday morning, students at Eastbrook High are gearing up to take their final exams ahead of the Christmas break. However, what starts as a gentle December snowfall soon escalates into a menacing winter storm, leading to an early school closure. Those students who can’t secure a ride home before the storm intensifies find themselves stuck in the school gym. Among them are six students who, though previously unfamiliar with one another, are left behind as the weather outside deteriorates and the school is locked down. As the night unfolds, they face challenges, forge new friendships, and uncover hidden truths, realizing they must depend on each other to endure the night.
