Nine-year-old Tony loves ghosts and horror stories, but when he's left home alone one night, he gets quite the fright as Rudolph the little vampire flies in! Soon the two are firm friends (when Rudolph isn't trying to bite Tony). Tony even visits the little vampire's Family Vault in the graveyard where he narrowly escapes the clutches of Rudolph's fearsome Great-Aunt Dorothy. But what will happen when Tony's parents try to invite his new friend for dinner...?
