"At the end of the century, the greatest battle has begun!"

The Futurians, time-travelers from the 23rd century, arrive in Japan to warn them of the nation's destruction under Godzilla. They offer to help erase Godzilla from history by preventing his creation. With Godzilla seemingly gone, a new monster emerges as the Futurians' true intentions are revealed.
