In this Japanese monster opus, the awakening of a volcano brings with it the return of Gaos, a huge creature that resembles a gigantic bat with powerful lasers. The creature begins raising havoc all over the island, but Gaos makes the mistake of attacking a plane whose passengers include a small boy in psychic contact with Gamera, a powerful, jet-propelled flying turtle. The boy cooperates with a group of scientists who hope that by combining their technical know-how with the boy's ability to control Gamera, they can wipe out the destructive super-bat once and for all.
