Plot:
Circus music plays as the credits roll.
The circus parades through the town.
The most annoying hateful child monsters act tough and decide to throw rocks at Dr. Bernard’s house. Note: OK, that is Boris Karloff and I’m just going to call him Boris
and doctor when needed.
Boris is able to grab one of the kids and lets him go. The esteemed doctor returns to the science in his lab and checks on his animal specimens.
At the general store, the lazy bums want to run Dr. Boris Karloff out of town. They think he used his patients as guinea pigs. The annoying brat brigade run in claiming Boris
went after them for no reason. Mason, the banker, is more heartless than a college scholarship officer renewing a scholarship. He also wants Karloff out of town.
When Boris walks in the general store slash pharmacy; everyone gives him the silent treatment.
Karloff checks on his neighbor’s daughter, Frances. She has polio and been unable to walk for 10 years. Frances also reminds Karloff of his daughter. He will make her
walk again.
Danny, Frances’s boy friend arrives. He has several many doubts about Karloff. Frances doesn’t believe the rumors about the good doctor.
Karloff has convinced Frances to go to the circus with Danny. The happy couple drives off.
At the circus, punk monster children talk about the gorilla.
Circus fun ensues with a smattering of trapeze artists.
After the show is closed for the night the circus workers are kicking back. The ape is being beaten by a trainer whose father was killed by that ape. Halliday, the ringmaster,
wants the trainer to quit bothering the gorilla.
Well, the gorilla is able to maul the trainer and escape the ape cage. It also accidentally starts a fire. The circus workers rush to put out the fire.
The trainer is taken to Dr. Karloff. He realizes he has a test subject for Frances.
Karloff’s lab notes reveal that spinal fluid can be used for his serum.
The sheriff has a posse ready to hunt the ape.
In the morning, Karloff visits Frances. He has the serum ready to be tested.
Mason, the evil banker, wants the sheriff to drop everything to serve a foreclosure notice.
Frances is starting to get some feeling back in her legs.
In his lab, Karloff accidentally breaks the other vial of the spinal fluid serum.
The ape is roaming about the countryside and being tracked by the posse.
The ape spies in Karloff’s lab before breaking the window and trashing the lab. Boris is able to kill it with one swipe of a scalpel.
The posse stops by to mention the ape is in the area.
Boris wants his maid not to mention that the ape is dead.
We get another scene where Danny doesn’t like whatever Boris is doing.
The posse is still on the job.
We see the Ape walk out of Karloff’s house.
At the home of the evil banker, Mason is about to leave. His wife knows about him cheating on her. He doesn’t care that she knows or even gets angry. Well, Mason
swaggers out and is promptly gotten by the Ape. Bless you killer Ape. Go after the hateful snotty monster children….
Back at the general store, the posse wonders what to do next. The bloodhounds react to Karloff.
Karloff is hard at work.
Danny thinks that Frances is getting worse with the pain she’s feeling in her legs. He wants to see Karloff who sees this as being able to help many people. However, Danny
loves Frances just as she is and doesn’t care about the suffering of other people.
The coroner has Dr McNulty check on Mason’s autopsy. He learns the townsfolk hate Karloff for his research and experimentation in the middle of a polio plague some
years back.
Boris sees that Frances is able to move her foot slightly.
Dr McNulty pays a visit to Karloff. He asks about spinal injections on the trainer and Mason. 25 years before, Karloff was thrown out of a medical foundation for his
theories. He has been trying to prove his theories this long.
They go to check on Frances. She is unable to move her foot at all. However, McNulty felt a muscle reflex. He asks for Karloff to return to the foundation. Boris will stay
here but keep them informed of his progress.
Ape goes out again.
The devil-punk-snot brats shot at the Ape.
The Ape heads home.
Several women are chewing out the sheriff about their missing kids who run in at that moment. The liar-hateful-snot monsters claim to have killed the Ape.
Boris is hard at work.
The sheriff stops by to talk with Boris. He wonders what could cause the Ape to stay around Karloff’s house for so long and why have the dogs barked at Karloff, too. Karloff
brings out the trainer’s coat and claims that is the reason. .
Frances has another session of trying to move her legs but still can’t walk.
Sheriff stops by the circus and checks with Halliday about the gorilla. What does it eat? He also learns that the trainer’s coat could draw the gorilla.
Boris is furiously working and has the maid hold onto his records. He needs one more.
Posse splits up into a number of groups. The sheriff starts to look for Boris.
Guys are on watch. The Ape manages to get one of the guys. The posse leaps into action. Somehow, the Ape is winged.
Frances spots the limping gorilla heading for Karloff’s house. She wheels herself out to warn the good doctor.
The posse is able to shoot the Ape again.
The sheriff checks on the ape and unmasks it to reveal Karloff.
Frances stands out of her wheelchair. The dying Boris sees her walk to him before expiring.
Later, Frances slowly walks to Danny. She has burnt her chair to never use it again.
