Sci-fi action sequel starring Liam Hemsworth, Jeff Goldbum and Bill Pullman.
Two decades after the alien attack on planet Earth, the world has pooled together to form Earth Space Defence (ESD), a global organisation designed to protect the planet from any further attacks.
With ESD personnel stationed on Earth, the Moon and Mars, they have spent the last 20 years developing technology that was salvaged from the previous attack.
Before their defeat, however, the aliens sent a distress signal back to their planet asking for assistance in the form of a more powerful army.
When the aliens receive the message they prepare for attack, and this time they are taking no chances.
