When aliens attack, they quickly and easily wipe out most of the human race in the first month of their coming. But a few remain, Gen Zygon one of them. Gen, a newly graduated adult from New York, has... skills, so to speak. But when he comes in contact with an alien, Gen realizes that though some aliens want to kill humans, not all of them are bad. Will Gen be able to resist the aliens? Will he and his new friend, Beck, live through another night in the alien-invaded Earth, or will they be wiped out like every other human and traitor?
