Overnight, it grows into a horrific monster that has doubled in size. In desperation, Calder calls in the Army to help fight the monster, which has taken refuge atop the Coliseum in Rome. But it will take more than man's weapons to fight the evil forces of the unknown and save the world from destruction...
