Godzilla is reunited with one of his arch-enemies in this remake of the Japanese monster classic. When a meteorite crashes to Earth in the Pacific Ocean near Japan, the consequences are remarkable; it manages to awaken the dormant monster Godzilla, it uncovers a huge egg that had been buried on Infant Island, and it revives Battra, a mammoth insect that destroyed a primitive civilization on the island long ago. Takuya (Tetsuya Bessho), an archeologist and adventurer, is sent to the island by representatives of a large Japanese firm in order to get the situation under control; joining him is Masako (Satomi Kobayashi), Takuya's ex-wife, who is also an executive with the corporation. On the island, Takuya and Masako meet the Cosmos (Keiko Imamura and Sayaka Osawa), a pair of tiny identical twins who are the last remnants of the civilization destroyed by Battra. It seems that the egg contains a descendant of Mothra, who was the great protector of their society, and the Cosmos believe that the presence of both Battra and Mothra indicates that the gods are angry. The egg is shipped back to Japan, but en route, the larvae of the giant moth hatches just in time to do battle with Godzilla, who (as usual) is in a bad mood and wants to break things. Godzilla makes his way to Japan and begins laying waste to everything in his path; Mothra and Battra set aside their differences and join forces to stop him.
