They've discovered that mythological creatures such as werewolves, vampires, witches, and satyrs were once real, and that these monstrous genetic strands are still present in human DNA. These radical scientists unleash the bestial side of human beings that had been dormant for eons, and within months, most people are dead, and bloodthirsty creatures rule the earth. Despite the fact that Dez McClane has no special powers, he is determined to atone for the lives he couldn't save and to save the woman he loves. But how long can a man survive in a world full of monsters?
