In the year 2019, a plague has transformed the majority of the world's population into vampires. These vamps aren't romanticized gothic heartthrobs who sulk in the dusk, but omnipotent overlords, ruling the earth's economy and social strata with an iron fist. Humankind teeters on the brink of extinction, in danger of being either turned into vampires or captured and farmed for its precious blood, sold at premium prices. Without a steady diet of fresh human blood, starved vampires feed on one another and regress into terrifying feral beasts. As demand outstrips the supply of plasma, attempts to find a substitute before time runs out have been failures. If humanity dies from the vampires' bloodlust, the dominant race will become savage animals.
