Wilks, Billie, and Bueller were the last survivors of a devastating assault on the aliens' home planet.  But once their retum to the solar system made them refugees once more, fleeing Earth and its alien infestation in a desperate attempt to stay alive.  Now, in an otherwise unmanned military transport, they hurtle through space.  Destination: unknown.

Nor do they know that they head toward a remote colony and military outpost.  This pocket of humanity at the very edges of space is at the mercy of a general names Spears with an agenda all his own.  Now Billie, Wilks, and Bueller face a new nightmare, and it is nothing they could ever have imagined: a gift of madness from an alien world, unbalanced mind, and the experiences of a mysterious pilot named Lieutenant Ellen Ripley.
