The Earth has been invaded by a race of aliens who are only interested in finding new slaves for their empire. This creates a problem for some of the other species living here-vampires and werewolves. The more humans they take off-planet, the less food they have. Humanity's fate is locked in between these two warring factions whose only desire is to retrieve their food source... so one way or the other, the human race is screwed. Vampires vs. Werewolves vs. Aliens-who will claim the human race as their own? Whoever wins... we lose.
