The Monford boys and Black sisters are use to undertaking temporal adventures and dealing with adversity using their paranormal skills. But this time the fate of the world hangs in the balance. They must work with the US military to battle a zombie outbreak that threatens to spread globally. Beginning in New York City, when a 3,000-year-old ancient hunter is inadvertently reanimated, the number of zombies quickly grows motivated by their desire to spread and become the dominant species on earth. In reality the zombie outbreak represents an alien invasion of zombie parasites brought to earth on a meteor made of gold. Once the ancient hunter is reanimated, he begins to infect unsuspecting New Yorkers. Soon there are almost a million zombies attempting to escape New York City. Circumstances brought about by the zombie outbreak cause a rogue Air Force Major to commandeer a B-2 bomber and drop three nuclear weapons on New York City and unwittingly spread the zombie parasites globally. What was once a regional outbreak has been transformed into an international outbreak threatening many countries. The twins must find a way of defeating the zombies using their brains and paranormal powers. In a race against time, Larry Montford must find a way of out witting the zombie leader or mankind is doomed.
