"TIME - 21ST CENTURY 

PLACE - AMERICA 

CRISIS - A WORLD GONE MAD 

PRESIDENT'S WARNING - 

DESTROY THE VITON MENACE - 

OR EARTH HAS ONLY 80 HOURS TO LIVE! 

Bill Graham was among the scientists and government leaders left who heard the president's message. He shuddered at the thought of the last Viton rampage of kidnapping, ghastly murder and madness. Hidden somewhere in the vastness of the galaxy, the hideous blobs of Viton, that fed on men's fears and emotions, planned a last-ditch attack to destroy the universe. Only Bill Graham had a one-in-a-million chance to stop them. But the Vitons were so deadly that even to think about them risked instant annihilation."
