normal school day turns tense when an anonymous threat forces the entire campus into lockdown. Doors lock, halls go silent, and students are trapped inside while no one knows what’s really going on. Inside one classroom, a small group of students from different worlds is stuck together as minutes turn into hours. At first, they wait for answers. But as time passes, fear spreads, trust breaks down, and hidden truths start slipping out. A quiet student begins noticing things others miss, realizing the situation may not be as simple as it seems. In a place where no one can leave, the biggest danger might not be outside the room—but the secrets inside it. As pressure builds, everyone has to decide who to trust, what to believe, and how far they’re willing to go to make it out together.
