For years, the site of the Great Pyramid in Egypt had been off-limits to explorers and the public. The government deemed it too dangerous and haunted for any visitor to enter. Eleven years ago, a group of brave explorers and their workers defied the ban and ventured into the site. But just a few days later, all were found dead under mysterious circumstances. One explorer's body was never recovered, but it was presumed that they too had met their end. After the tragic discovery, strange lights began to be seen around the Earth, and unexplainable events started occurring all over the globe. For nearly a year, chaos reigned as people tried to make sense of the inexplicable occurrences. And then, suddenly, everything returned to normal without explanation. Now, ten years later, three new explorers have been granted permission to investigate what happened so long ago - an event that still remains shrouded in mystery and fear.
