A research biochemist receives a package from a fellow scientist containing profiles on six people suffering from an unknown disease, plus tissue samples for study. Both scientists are found dead shortly thereafter and all trace of the file and samples have vanished. A space mission to study an unusual comet passing through our solar system brings back something far deadly that the usual samples of space debris - and Michael Raines, who had been involved in a government study about the use of telepathy in space research and communications, finds his powers becoming unreliable as he stumbles across traces of a massive conspiracy that reaches from the heart of a comet all the way to the Oval Office.
