Alien visitors arrive on Earth, declaring themselves to be peaceful. They appear to be friendly, and they are virtually indistinguishable from humans physically. Not everyone is convinced that they have good intentions, however, and a small pocket of resistance develops as some make the awful discovery that these aliens plan to suck the Earth dry of its natural resources and annihilate humanity once they have no more use for it. Those who know the terrible truth will stop at nothing to expose it and fight to keep the aliens from destroying the planet. However, it's hard to fight an enemy when it is so difficult to even know who is human and who is an alien. A dangerous road lies ahead for all of humanity.
