Gamera vs. Jiger

When a giant stone statue on Wester Island is disturbed, the legendary monster Jiger appears and heads for Japan, threatening to destroy the Expo '70 world's fair in Osaka. Gamera tries to stop this new rival, only to be injured when Jiger lays eggs inside of him, leading two boys in a submarine on a perilous quest to save their hero from within. With the help of giant speakers and white noise, the children successfully destroy the infant Jiger and revive Gamera, allowing them to defeat the monster in an epic final battle that ends with Jiger's destruction.
