The aliens return to complete their plan of human domination, launching a second wave of attacks that threaten to destroy what is left of humanity.

Two years after the Martian invasion, George Herbert's worst fears are realized: The Aliens have returned. As a second wave of Martian walkers lay waste to what's left of Earth, an alliance of military forces prepares a daring attack on the Red Planet itself. Once again, the future of mankind hangs in the balance.—Eric Forsberg

It all started with the 1st invasion, none saw it coming. For most, it was just a normal day on earth. The aliens came, they saw, they ate, they were defeated by a virus. Here we are 2 years later. Once more, humanity is on the brink of extinction at the mercy of the alien invaders. In the beginning, several people were on the run from a tripod that was seen firing a laser transport ray at them. Among them was George Herbert. Not long after the tripod abducts George's son. Son after, Pete finds himself and George stuck inside the ship, hooked up to the Harvesting Unit. George and Pete are freed. George gets caught again and is now infected. He is hooked up once more. Pete must find him fast or his life is over. The ending scene shows a final invasion being revealed as the film ends. -Ada Welch
