A human-created virus has infected humankind, mutating most into super strong, near-immortal vampiric creatures. The "virals" - also called "jumpers" - and "dracs" (after Dracula, of course) - can leap 20 feet through the air at a bound and split a human (or a horse, or a cow) in half with their bare hands. A small band of men and women embark on a cross-country trek, looking for a way to protect the few remaining uninfected humans from extinction. With them travels an enigmatic prepubescent girl who talks to the virals with her mind and seems to have been born 100 years before.
