A group of middle schoolers eagerly begin their first overnight adventure with the S.T.E.M. Scouts, an inclusive, STEM-focused scouting group. But excitement is tinged with unease - years ago, two scouts mysteriously vanished during a similar event. For safety, the kids are locked inside the school’s phys ed wing and promised a night of fun and learning. When they decide to play a game of Manhunt, the night takes a dark turn. One scout witnesses a suspicious exchange between a creepy Scoutmaster and the school janitor. Intrigued and alarmed, the group investigates - uncovering a hidden science lab, a chilling experiment called “Project Atlas,” and a web of secrets tied to the missing children. Trapped and unsure who to trust, the S.T.E.M. Scouts must rely on their courage, a repentant ally, and the strength of their friendship to survive the night - and make it to sunrise.
