While nations of the world combine forces, the alien air force clears the skies then blasts military targets around the world, following our own radar signals before moving on to attack the infrastructure of our society, leaving one last hope: nuclear weapons. Somewhere in the Atlantic Ocean, a submarine releases a Trident II ballistic missile, carrying nearly 3.5 megatonnes of destructive power. The missile breaks apart into eight self-guided warheads. But, Earth's mightiest weapon has no impact. From shielded bunkers and secret locations, surviving military leaders issue orders for a surprising new tactic. Instead of attack, they order their forces to run away.
