Communication attempts are futile, and the world quickly learns the aliens' hostile intentions when a powerful attack is launched, decimating the cities below with no warning. Amidst the chaos, different individuals converge with the shared goal of survival. A skilled fighter pilot, his girlfriend's family, and a motley crew of survivors find themselves thrust together in the looming shadow of the alien menace.

As the government scrambles to respond, a brilliant but quirky scientist uncovers a critical weakness in the seemingly invincible alien shields. The President of the United States faces a dire situation: orchestrate a counter-attack against a technologically superior enemy or submit to the annihilation of the human race. With the fate of the world in the balance, a risky plan is set in motion to use the information discovered by the scientist, requiring coordination and courage from citizens and soldiers alike. Together, they prepare for a last stand — a fight not just for their lives but for the independence of Earth itself.
