Terra of the future looks pretty good overall and Earth along with a few space stations are united under one representative government. The largest threat to that security is an enigmatic alien race, the Greys, that likes to kidnap humans for an unknown purpose. Although technologically stronger the Greys are vulnerable to powerful psionic attacks which has made the psi guilds prominent in the space navy. For that reason the government and the space navy take it very seriously when precogs all over the globe start reporting visions of navy personnel encountering at least one new race, and possibly two. Based upon those visions the navy launches a new set of exploratory missions including a crew made up of six people seen in the visions. Unfortunately for them, the visions all agree that there will be a crew of humans at the mercy of a hostile race that intends to eat them alive.
