Ancient Aliens: Season 3, Episode 14

3 - 14: Aliens and the Undead

Zombies rising from their graves... Blood sucking vampires damned for all eternity... and humans trapped in a life and death struggle between heaven and hell. For thousands of years, mankind has told tales of encounters with strange, soulless creatures. Are these beliefs merely manmade fabrications--or could there be extraterrestrial origins in earthly encounters with the undead?
