A screenwriter falls in love with a Mexican woman while searching for a story line south of the border.

Fact and fiction collide in this exploitation flick that employs documentary footage depicting the bizarre self-flagellation rituals of the fanatical Catholic sect known as the Penitentes. Mixed with those truly disturbing sequences is a story concerning a killing in New Mexico, itself inspired by the murder of real-life reporter Carl Taylor as he worked on an article on the Penitentes.

Dr. Frankenstein and his monster both turn out to be alive, not killed as previously believed. Dr. Frankenstein wants to get out of the evil experiment business, but when a mad scientist, Dr. Pretorius, kidnaps his wife, Dr. Frankenstein agrees to help him create a new creature.
