Frankenstein's daughter, Freda (Gina Romand), whose favourite pastime
is of course putting humans together from bodyparts & transplanting
gorilla-brains into human bodies, stays forever young by a self-dveloped
youth-serum. But the serum's formula is deteriorating, so she comes to
the conclusion only Santo's blood can give it the lasting quality she
so longs for, 'cause you see, Santo has now the same reflexes he had 30
years ago, so there must be something in his blood to keep him young (as
a matter of fact, by the time this movie was produced, Santo really had
a 30-year-long career as a wrestler behind him).
To lure Santo into
her trap, Freda decides to abduct his girlfriend Norma. Of course, the
trap springs, & Santo is soon subjected to torture at Freda's hand -
she even unmasks him when he's chained up - we don't get to see his face
though - & kisses him (not exactly torture, that), then has him
fight her monkeybrained (literally) creature (Gerardo Zepeda), a fight
that Santo wins of course. When Freda hypnotizes Norma into gouging
Santo's eyes out though, he can with the help of his honest love break
Freda's hypnotic spell & break free.
When Santo, Norma & her sister Elsa
(who went along for the ride) are escaping, Santo has to fight several
of Freda's minions & her new creature Ursus (played ba Gerardo
Zepeda again), who he fatally wounds, in a graveyards. With the girls
sent off to safety (or so he thinks) he returns to Freda's hideout, to
save the girls again (of course they have been recaptured) & destroy
the cavernous laboratory once & for all - this time with the help of
Ursus, to whom he has shown great compassion.
In the end, as only Santo,
Norma & Elsa escape, Freda ages a hundred years before the eyes of
her assistant Roberto Canedo before the whole place is blown up ...
& Santo comes back to the city just in time to win the wrestling
As you might have guessed from the synopsis,
this is pure pulp cinema, with all the familiar trappings - (wo)man-made
monsters, gorilla-braintransplants, youth serums, underground
laboratories with self-destruct switches, acid thrown into faces, &
a wrestling superhero thrown in just for good measure. In other words,
pure mindless fun.
