A 19th century scientist is hung after transfusing blood from young women in the quest for eternal life. His grandson revives him to continue his experiments. The original scientist impersonates the gandson to continue his work, with both parts being played by Fernando Casanova. Most of this film is a Mexican horror film that Jerry Warren added a few English language scenes and English narration voice over for the Mexican dialogue. The film ends up as a strange mix. Rock Madison is top billed on the credits but is a made up person.
