In this Japanese sci-fi film based on the prophesies of the French seer Nostradamus, the story begins in 1999, the year the prophet predicted the world would end. The future world is horribly polluted, and one scientist is assigned to deal with the giant blood-sucking slugs that have been spawned by the toxic filth in the ocean. With their presence, almost all sea-life dies, the Earth's plants shrivel up, and children begin to expire. At this point, the common folk begin to riot until the governments call in the military to stop them.
