A martial arts expert turned wilderness guide has to defend her tour group against two killers out to retrieve an incriminating videotape.

National Vampire is a feature-length documentary that explores vampire culture in the United States. To achieve this, the filmmakers spent more than two years traveling around the country, attending vampire-related events, and interviewing dozens of people involved in the vampire community. Shooting locations include a Vampire’s Ball held in New Orleans each Halloween, a vampire tour of San Francisco, and a New York City shop that “transforms” people into vampires. Also featured are a vampire “dentist” who makes fangs for a living, vampire role playing gamers in Dayton, Ohio, a vampire-themed magician, and a bloodthirsty Texas couple that claims to be the real thing. Going beyond the surface, National Vampire also explores a number of subcultures that overlap the vampire community, including the goth music scene, bondage and S&M, and blood fetishists who take part in piercing and full-body suspension rituals.
