OPIS
Robert Neville as the last living man (ie not infected by a 70s plague) fights off vampires whilst trying to survive a la Robinson Crusoe (boarded up house, freezer full of food and a fine collection of classical music LPs - his desert island discs?). He has a hard time coaxing a frightened dog inside. When it's in, the creature companion dies within a week. A Man Friday - in the form of Ruth, a widow, appears. She turns out to be a moral double agent. Attracted to Neville and his uniqueness as the uncontaminated one, but also employed by the vampires who are mutating into a new species.
