A group of archaeology students set off on an excavation trip with their teachers. The team, who are heading to a previously determined area, are very excited. Everyone begins working on the excavation with enthusiasm. Shortly thereafter, one of the students discovers a magical object during the excavation, which turns everyone's lives upside down. The team's joy gives way to fear as night falls. With nightfall, the only way for the seven-person group to escape is for morning to arrive.
