Class 5 had just concluded an educational excursion to the Atami Training Center of the National Aerospace Laboratory. As the students made their way back to the buses, they realized they had lost their bearings and began searching for a way out of the facility. Before they could locate the exit, a sudden and violent earthquake struck without warning. The tremors brought the structure down around them, leaving the entire class buried beneath a massive pile of rocks and debris. Now trapped in the suffocating darkness of the collapsed building, the students face a terrifying reality. None of them want to die, yet their options for survival are severely limited by the wreckage pinning them down. With no immediate hope of rescue and the constant threat of further collapse, panic begins to set in among the classmates. Forced to confront their own mortality in the ruins of what was supposed to be a routine school trip, the students must figure out how to endure this desperate situation or perish together in the dark.
