Plot:
We see Gamera fighting various monsters.
In a harbor, Hiroshi is waiting to go out. His dad is refitting a submarine that can only dive 3 feet underwater. Muraco, Hiroshi’s sister, is dating Kayzuki who is a
engineer for the new theme park, Expo-Land. Kayzuki is going to take Hiroshi to tour the park.
Before leaving, Hiroshi gets a postcard from a friend whose dad is going to bring an idol on a small island to Expo-Land.
Narration about how great Expo-Land is begins. Future fu. Apparently, the idol is to symbolize the past. Kayzuki learns that the island’s inhabitants refuse to have the
idol, Devil’s Whistle, moved. Kayzuki tries explaining by a slideshow how a time capsule about Expo-Land will be opened in 5000 years. The native leader storms out.
On the island, the crew readies to move the statue. When Gamera flies in, he keeps the statue from being moved. The crew opens fire on the friend of all children. Gamera
lands nearby.
The crew quickly airlifts the Devil’s Whistle away. Suddenly, a nearby volcano erupts.
The statue is on the ship heading for Expo-Land.
In the city, Hiroshi meets with his friends: Susan and Tommy. They are the kids of the statute mover. They tell how Gamera tried to kill them and don’t have Hiroshi’s
faith in the friend to all children.
Back on the island, the volcano is still smoldering. Jiger, a sort of four horned triceratops rises from the rocks. Gamera lands and the fight is on. Flying kaiju turtle
ensues. Jiger is able to knock Gamera on his shell and swims away. Yes, the hero just got flipped on his back and can’t right himself.
The ship’s crew that has handled the statue has gotten sick. Kayzuki is able to convince some of the dock workers to help transport the idol to Expo-Land.
The ship spots Jiger charging at it and torpedoes the ship.
Choppers lift the statue away as Jiger sinks another ship. Model city fu ensues.
Everyone watches Jiger terrorizing the city on television. Apparently, the statue was used to keep Jiger inactive. The monster will try to destroy the idol at Expo-Land.
Gamera is still on his back and trying to right himself to no avail.
No jokes must be made about turtles earning money on their backs
Jiger rampages with no force able to stop him. He uses his death ray on the military.
Could you direct me to the nearest William Castle movie?
The city readies to evacuate. Hiroshi is positive that Gamera will arrive to save the day.
Finally, the turtle is able to right himself and flies to the rescue.
Evacuation ensues as Jiger keeps reducing city property values.
Nothing can stop Jiger.
Hiroshi, Tommy, and Susan spot Gamera flying in.
Rematch ensues between Gamera and Jiger. Sweet kaiju action ensues. Jiger impales some kind of needles into Gamera who walks away in agony before collapsing.
The kids spot Gamera at the bay. The giant turtle changes color and seems to freeze solid. They think Gamera is dead.
Apparently, Expo-Land is more worried about losing numbers of reservations than the giant monster destroying the city. They then discuss the dangers of a rampaging
giant monster. No weapon can seem to stop Jiger. Dr. Williams has been hearing a strange tone from the idol. Tommy and Hiroshi hypothesize that the idol has some sort
of poison on it.
Jiger is heading for Expo-Land to the mountain where the idol has been placed. Jiger uses his suction powers to throw the idol in the ocean.
Hiroshi and Tommy convince the scientists to examine Gamera.
X-Rays of Gamera reveal him to filled with Jiger’s larva. The only answer is surgery. However, with Gamera not having health insurance, the doctors would rather let
him die.
Tommy and Hiroshi sneak out. They hatch up a plan and have to distract Hiroshi’s Father and Muraco. Susan is sent to deliver a message to Kayzuki. Tommy and
Hiroshi steal the sub and pilot it into Gamera’s mouth.
Kayzuki reads the note they had Susan deliver.
Fantastic Voyage ensues. The sub gets lost in the stomach and makes a wrong turn at Albuquerque. They get radio contact with the scientists who direct
them to the lungs. Debarking, Hiroshi and Tommy find the monster larva that seems to have been growing and chases after them.
Retreating to the sub, they discover that radio frequencies disturb the larva.
Everyone is on he dock and see the sub leave Gamera’s mouth.
Tommy and Hiroshi tell the scientists about the radio frequency weakening Jiger. The idol has a hole like a whistle. The idol can generate a sound that attack Jiger.
The kids want Gamera healed. A plan is developed to use an electrical current to jumpstart Gamera’s heart.
The speakers are readied to attack Jiger. It takes several attempts to find the correct frequency.
The cardio-resuscitation of Gamera is to begin. The power plant is operating at full power to revive the flying turtle. When the plant overloads, Expo-Land loses the
speakers generating the sonic frequency to incapacitate Jiger.
The kids cheer on Gamera’s recovery. He flies away to finish off Jiger once and for all.
Everyone watches the battle for all.
Gamera is able to evade the spikes unlike earlier and Jiger’s death ray.
Gamera’s fire breath is starting to drive Jiger back.
The kids cheer like at wrestling match as Gamera picks up Jiger and drops him from mid-air. Gamera gets a hold of the idol.
The sounds incapacitate Jiger. Gamera tosses the idol in Jiger’s head who quickly dies.
Everyone cheers.
Gamera flies away carrying the trash of Jiger’s body with him.
You will believe a giant rocket powered turtle will dispose of his enemies...
Expo-Land is opened. The adults have learned to keep the faith of child or some pointless moral.
Gamera flies away into the sunset.
