If the demons can remain on the Plateau for two days, they will permanently replace the explorers, and Kayle will be free to bring chaos and destruction to the world.

Drummond has been stranded for five years since the crash, protecting the plane's cargo—a crate of iridium ingots stolen from the Royal Navy. Challenger is astounded to see the iridium because it had been intended for his secret wartime research. The sight of it prompts him to remember the night five years earlier, when he was questioned about the theft by two British intelligence agents working for MI5.

Throughout the twists and turns, we find out that there may be more than just coincidence that has brought our small group to the plateau.
