Santo vs. la hija de Frankestein

SYNOPSIS

Dr. Frankenstein's female descendant is an excellent mad scientist in her own right. At a ripe old age, she discovered that the blood of the supernatural wrestling hero, Santo, is a youth elixir. For years she has been periodically injecting herself, and her henchmen, with a serum made from the blood she wiped from Santo's nose. But now, her body is so saturated with the serum that she needs frequent painful injections to maintain her youth. Before the serum stops working completely, she needs to experiment on more of Santo's blood. Instead of attending another wrestling match, and hoping for another nosebleed, she has her lackeys kidnap Santo's girlfriend. Santo, of course, comes looking for her. What he'll find is a spooky underground cave, filled with corpses, bats and flying daggers. A half-man-half-gorilla will cause him trouble. But his ultimate battle will be with Frankenstein's old monster, yet again brought back to life.
