Five small-town school friends celebrate Halloween with an overnight adventure into the legendary “haunted” Jarvis Mine. Local legend tells of the angry spirits that have occupied the mine since a family was murdered for still mysterious reasons exactly 100 years ago. But that doesn't stop these young adrenaline junkies from exploring the unknown — and bringing mini-cameras to capture their every move. Yet once deep into the mine their best-laid Halloween plans go awry, leaving the adventurers trapped without escape. Are their misfortunes purely accidental or is the legend true and something more lurks in the darkness? Nothing is what it truly seems as the past and present collide in this psychological thriller.
