Plot:
A man is hit on the head and carried away at night.
Credits roll...
The Wax Museum has another group going through it. Doctor Karol is telling the crowd about the dummies. Guillotine (inventor of the guillotine), Ghandi, Stalin, Pancho
Villa, and Gary Cooper...All of them are historical figures. But, I never thought that Gary Cooper was on the same level as Ghandi and Stalin...Susan the photographer
is taking pictures for an article to be written by her soon to be brother-in-law. They go to everyone's favorite part of the wax museum: the scary part.
That night, Dr Karol is over at Professor Halpin's lab. (To be fair, I never heard them use the Professor's last name) Some high tech video equipment starts up: the video
phone. Samson is contacting the Professor about his last case. Samson discovered that one of the Professor's colleagues was murdered by an unnamed foreign
power. Professor explains about Samson to Dr. Karol. He's a man of mystery and no one knows his name or his face for that matter...
The next afternoon, Susan is taking pictures in museum alone. She has that feeling that something bad will happen. Creepy music starts to play. Cheap scare time as
Susan is scared by the sudden appearance of Doctor Karol, who starts his creepy rant about how monsters exist...
Susan decides to get out of there while the getting is good. As she's leaving, it is already dark outside, and Susan isn't alone. The ambusher from the very first of the
movie sneaks up on her and grabs her. In the process, Susan drops her camera which is found by a couple of little old ladies. Her sister, Gloria, and her boyfriend,
Charles the reporter are beginning to worry about Susan. One of the little old ladies that find the camera returns it to the address on it which is where Gloria and Charles
are. This is proof that something is wrong. They go to the police to have them look for Susan. They all go to the wax museum to question Dr. Karol.
Dr. Karol goes back to the Professor's lab. Everyone suspects Karol behind the string of disappearances including Susan. Samson could prove that Doctor Karol is
innocent and find who is ruining his good name. Well, he could, but Samson has got a match to wrestle. 2 falls out of 3. Mexican wrestling. Yeah, mat wrestling none
of that luche libre wrestling. Old school stuff...The heel starts fighting the crowd after being thrown out of the ring. He gets back into the ring and Santo pins him. The
match continues as Samson has to pin him again. Finally, we learn for sure that Samson is actually Santo. The movie maybe badly dubbed. But, they don't dub over an
auditorium full of wrestling fans screaming "Santo"....
Dr. Karol convinces Samson to help him prove his innocence. Samson agrees as a knife is thrown at Karol. Samson chases the would-be assassin down and starts to
wrestle him. Wannabe assassin is street fighting while Samson is using pins and holds. But, who's going to count the guy out Santo and raise your hand in victory? The
wannabe assassin manages to escape.
Meanwhile elsewhere, someone is sneaking into an apartment. With catlike grace, he moves in the dark, his cape gently flapping. Gloria and Charles come into the
apartment. Santo pins Charles, who isn't that angry about it. Who would be disturbed if he were attacked by a guy in a mask and cape? Well, they ask Santo why he's
looking into the case. Charles has dug up some research on the good Doctor Karol. Karol was in WWII and hideously disfigured. Charles is extremely suspicious of
Karol. Santo went to the apartment for Susan's camera to check it for fingerprints in his lab. He's got a lab? Santo has a Bat Cave?
Just so you don't forget. Karol reads the Professor a threatening letter that was sent to him. The writer threatens to burn his museum down. Professor has been asking
Karol if he has any enemies. Apparently, during the war, Karol did something which angered some people. He's being very vague about it. These mysterious enemies
sabotaged one of Karol's earlier labs which resulted as Karol being disfigured on his hands and chest. What was he wearing when the accident occurred? Don't doctors
have plenty of protective wear when working with whatever Karol was?
Santo is examining the letter that was sent to Karol in the Santo Cave. Bat Cave...Whatever he calls it... He compares the letter to one that was typed by the Professor.
Both of the letters match identically. So does, that mean the Professor is behind everything. Santo uses his video phone to call the Professor and leaves a message on
the reel to reel answering machine. Doctor Karol is working on another wax dummy. Santo talks to him trying to find the Professor who was to attend a lecture with
Karol. Santo would investigate now but, he's due at the arena for a match. Wrestling time again. Italian cannibal movies have gratuitous scenes of animal
cruelty. Mexican wrestling movies have gratuitous scenes of wrestling. But, the only time Santo isn't wearing a cape is when he's wrestling.
Back in the wax museum, Doctor Karol goes into his secret lab. It has the standard mad scientist chemistry set with the giant bubbling tank which comes separately. We
learn that Professor Halpin was captured by Karol's lackeys. So, officially, Doctor Karol is evil. Karol doesn't like having to kill Halpin because he's a true friend. This
doesn’t seem to bother Karol as he has set the Professor to take the fall for the disappearances. And has the Professor thrown into the bubbling tank of wax. Doctor
Karol is ranting about how he's creating a new world...Blah, blah, blah... Susan is brought into the lab. Karol talks about how he'll make her ugly. It turns out some of his
wax monsters are alive. Not the famous ones like Frankenstein, just generic ugly ones.
Santo calls the chief of police trying to find the Professor. He doesn't think the Halpin is to blame. Santo asks the cops to search the wax museum again. Detective
masked wrestlers have a lot of pull with the cops. The police search the museum again. The cops close the wax museum to protect Karol and everyone else as
well. Karol sneaks into Halpin's lab and uses the video phone to spy on Santo. Charles calls Santo. Is Santo's lab an unlisted number? Apparently, Karol's face hasn't
changed since WWII. He looks the same age for almost 20 years. Earlier, Charles thought it was someone impersonating Doctor Karol. Santo reveals he thinks Karol
isn't as innocent as he appears. But, Santo has another match. Wrestling again...Santo jumps from the ring.
Susan awakens in the lab. Understandably, she freaks out when she sees Karol's evil lackeys. Doctor Karol sends his lackeys to kill Santo. Susan begs for death. Karol
begins a series of injections to turn Susan into a panther girl. We can only assume this won't be the cute cat girl we've learned about in anime. This would be a safe
assumption with the way Karol hates beauty. And with the way Karol wants to punish the beauty in others. Ok, he's got some serious issues. A good thing he doesn't
think about a person's inner beauty.
In Santo's secret lab, Santo is examining the photos from Susan's camera. The lackey's come around through the side door. This secret lab isn't a very good secret. I
thought the secret lab Spiderman had in his basement was lame. How did they manage to get all the equipment installed right under the nose of Aunt May? Better, yet,
why did Aunt May allow Peter Parker to live in the basement with Iceman and Firestar? Now back to the movie. And, it isn't even a cave. Santo's spider sense gets
him to turn off the lights and take cover as the lackeys open fire. These are some pretty bad lackeys. They do a bad job of killing Santo. Kick him while he's down and
run away. But, Santo is in hot pursuit. The fight continues. Somehow, it doesn't seem very farfetched for a guy in wrestling tights and a cape to fight 2 guys in the park
at night. The Max Shreck looking Nosferatu lackey throws a knife in Santo's back while he's fighting the other minion. The cops come to the rescue and chase the
lackeys away.
Karol is happy about the death of Santo. That only leaves Charles and Gloria to eliminate. Karol puts a handkerchief on the phone to impersonate Santo and calls Charles
telling him he has evidence against Karol and wants to meet. Charles calls Gloria tells her about the meeting and if he doesn't contact her in a couple of hours call the
cops. At least, Charles has the sense to carry a gun. The cops bring Santo to his lab. Karol is using the video phone to watch the cops over the lifeless body of
Santo. When the video phone's antenna stops rotating, Santo jumps off the table. He had to fake his death when he learned he was being spied on in his lab. Charles
pulls the gun on Karol demands to know where Susan is. He didn't believe it was Santo on the phone. More than that Santo's car wasn't parked in front, how can you
fool these reporters. One of the lackeys sneaks up and disarms Charles. Well, Gloria is worried and starts calling the cops. While waiting for an answer the other
lackey grabs her.
In the truly secret lab of Doctor Karol, Susan, Gloria, and Charles are captured. I am not going to comment on the underlying meaning of chaining Charles to the Wall
and strapping Susan and Gloria to gurneys. Santo is driving the Santomobile, sporty little convertible, to the museum. Karol explains the how the process works. Some
type of Rube-Goldberg contraption carries the liquid through a series of tubes and eventually through a showerhead which will convert people into wax dummies. Doctor
Karol is talking about how he gets off on the suffering of others. Santo is coming to save the day. The liquid slowly travels through the tubes. Santo is slowly getting
there. The wax monsters are starting to get antsy in there cages. The only thing slower than Santo getting to the lab is that liquid going through the tubes. Santo jumps
through the window and lands on Nosferatu. Karol's secret lab has a window? Santo manages to wheel Susan's gurney out from underneath the showerhead which
dispenses hot wax...
Santo keeps fighting the lackeys. Chemistry set finally is toppled and explodes. Santo manages to throw one lackey into the vat of wax, which is where Professor Halpin
is residing. Karol hightails it out of the lab into the hall of horrors. It is Santo versus Noseferatu. Well, Nosferatu gets electrocuted when he crashes into a fuse
box. Doctor Karol is whipping the monsters. Santo is untying everyone. Santo has to fight through all the wax monsters to get at Karol. Apparently, the monsters aren't
that effective. They turn on Doctor Karol. As the monsters slowing start heading in the lab, Santo has to fight them all. Santo manages to get them all into a pile and
pours the hot wax, remains of Professor Halpin, and the remains of one lackey on them. But, we don't see any trace that people were thrown in the vat.
The cops finally arrive at the scene. Everyone is happy and Santo drives off in the Santomobile...
