In Gamera vs. Jiger, Gamera has his hands full right from the very beginning. Japan is preparing for Expo '70, to be held in Osaka. Construction of the various buildings and pavilions is well under way. On Wester Island in the Pacific Ocean, a large statue of mysterious origin (called the Devil's Whistle) is located by scientists. Workers from the Expo are interested in returning the statue for display and try to remove it for transport by ship. The removal of the statue is hampered first by a tribal member of the Wester Island people, then by the unexpected arrival of Gamera, who aggressively attempts to prevent the removal of the statue, only to be shot at by the crew instead. The statue is removed from the island successfully after a volcano erupts.
Shortly after departing the island, members of the ship's crew begin to fall ill. The statue appears to be the source of the outbreak, as it makes a continuous piercing sound, driving many of the crew members insane. Later analysis reveals the presence of a central shaft that runs nearly the length of the statue top-to-bottom. The position of the opening on the statue is creating the high-pitched "squeal" as air passes through it.
Meanwhile, Jiger is actively seeking the statue, because it is making a horrible ringing sound that is causing her tremendous pain. Jiger lets nothing impede that hunt as she splits two ships in half and starts tearing through Osaka. Scientists are beside themselves as Jiger displays another weapon: a heat ray that vaporizes not only flesh but entire city blocks. The JSDF does make a token effort to kill the kaiju, but her quills knock down the F-104 Starfighters, ending that involvement.
The scientists are checking out possible causes of the noise, as it affected humans, causing temporary insanity. The children convinced them to do a medical exam on the comatose Gamera, where it is discovered that there's a dark spot on one of his lungs. One of the scientists served as a zoo director and realised that the spot might not be a fast spreading cancer, but actually a parasitic infant Jiger growing inside Gamera. An operation is needed to remove the threat, so the children took the initiative by taking a walkie talkie and a mini-sub. Communication is established with the kids and they enter Gamera through his open mouth, and after almost going into his stomach, they arrive at the problem lung. The children are able to exit the sub and walk around in the lung. There, they discover the baby.
Jiger is kept still by the speakers playing the white noise. It is not enough to kill Jiger, but buys enough time for the other plan to start. Gamera is subjected to high voltage shock before the electrical grid overloads. It is enough that Gamera revives on his own.
