A scientist experimenting with past lives finds a reincarnated Aztec who can lead him to lost treasure—and to a creature that should remain lost. (Composed of footage from two unrelated Mexican horror films, LA CASA DEL TERROR and LA MOMIA AZTECA, plus new American-made footage.)

El vampire y el sexy (or Santo in the Treasure of Dracula in its censored version) is a 1968 Mexican film starring El Santo and directed by René Cardona. ​The Vampire and Sex was filmed as the adult version of Santo in the Treasure of Dracula. While the censored family version was distributed in 1969, the uncensored version was not shown to the public until 2011 when it was discovered.

The Panther women are worshipers of Satan and perform rituals in their honor and sacrifice. The fighters will face them up and down the ring.

Innocent women are being kidnapped and used as guinea pigs for a brain transplant experiment. The diabolical Dr. Frankenstein continues his quest to perfect his brain transplant operation to bring back his deceased wife at any cost - even if it means playing with the lives of others. El Santo and Blue Demon are called in to help when their friend Alicia becomes Dr. Frankenstein's next target. It'll take both heroes to go up against the dastardly doctor and go mano a mano with his super strong zombie Golem.

When Santo accompanies a troupe of archaeologists in the search for Aztec artifacts, they find the Mummy of an Aztec who leaves a warning to those who tamper with his resting place. The adventurers ignore the warning, and before long, the Mummy starts bumping them off one-by-one with his bow & arrow.
