The largest underground nuclear test is to take place at a secure military installation, but its chief of security, Major Graves, suspects that the base may already have been infiltrated. After sending for David Vincent, Graves reveals that his friend Spencer, a civilian employee at the base, recently saw a flying saucer land, which was then met by one of the installation’s most important technicians, Carl Wyeth. As Vincent begins his investigation he uncovers the truth behind the invaders’ latest scheme - to detonate an anti-matter bomb that will knock the Earth off of its axis…
