I Am Legend

Robert Neville is the last living man on Earth...but he is not alone. Every other man, woman, and child on Earth has become a vampire, and they are all hungry for Neville's blood. By day, he is the hunter, stalking the sleeping undead through the abandoned ruins of civilization. By night, he barricades himself in his home and prays for dawn. How long can one man survive in a world of vampires?
