 Several young men arrive at a remote warehouse in San Francisco in expensive cars. One of them, having been given a dose of LSD, is left behind by his friends to face an unknown horror waiting in the darkness. A few days later, Frank is called to San Francisco when piles of ashes, possibly the cremated remains of humans, are found in a public garden. They also find links to the missing son of Chechnyan immigrants, whose last contact with his parents was a letter talking about the coming fires of Gehenna. While investigating, Frank takes the time to confide in another member of the Millenium Group, Mike Atkins, about the mysterious pictures of his wife and daughter that have started arriving at his house again.
