[3] El Santo travels to the past with the use of a time machine of his own design in search of the treasure of Count Dracula.
In both versions, El Santo and Luisa (Noelia Noel) face Dracula (Aldo Monti) and his entourage of vampires.
At the time of production, it was a common practice to shoot two versions, one family-friendly, the other adult-oriented for primarily European distribution.

The family-friendly version of the film is featured in the 13th-season premiere of Mystery Science Theater 3000, which first aired in March 2022.
