Psychiatrist Dr. John Holden travels to England for an international scientific conference, where a colleague, Henry Harrington, plans to deliver an exposé on devil cult leader Julian Karswell. Upon arrival, Holden learns that Harrington was killed the night before in a freak auto accident.
Holden, who debunks paranormal phenomena, decides to delve deeper into Harrington's research, hoping to expose Karswell's phony supernatural power----which he believes is simply the result of autosuggestion and mass hysteria, and is being used as a ruse to stop people from looking into the man's affairs.
After the investigation leads to a rare book on the occult, The True Discoveries of Witches and Demons, Holden is warned that if he doesn't stop digging, he'll die on October 28th at 10PM. It's then that he discovers a piece of parchment that has somehow ended up in his possession--on which is written a series of indecipherable runic symbols.
