Tourist gets bonked on the head, suffers an amnesiac fugue, wanders away from her husband and children, becomes an evil prostitute-y thief-y saloon gal.

A group of international criminals steal a large emerald from a heavily guarded Colombian mine and they plan to sell it on the black market. Unfortunately, the evil Dr. Igor is also manipulating other criminals, as well as the ones who stole the emerald, for his own benefit. Santo, a Mexican wrestler/Interpol agent works with the Colombian authorities in an attempt to recover the emerald and to stop Dr. Igor and his subordinates, as well.

A group of beautiful female vampires lure men to their estate so they can feed on their blood.

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.
