Four childhood friends are still bound to one another, and sometimes they go hunting together. They share one more thing — weak telepathic abilities granted to them by another childhood friend, Duddits, a young man with Down syndrome who is now on the brink of death.
Meanwhile, an alien spacecraft lands on Earth, bringing with it a terrible contagion — the red weed byrum.
The raving of a strange, deranged man who bursts into the four hunters' camp is only the first step the four friends take into a world of nightmare far beyond human comprehension. Into a world of utter Hell, ruled by Evil. Absolute Evil, come to bring destruction and fear upon mankind.
