Alien Siege (2018) Timeline Explained – Every Event in Order

The Kulku are dying from a deadly virus ravaging their homeworld. Their species discovered that human blood contains properties that can create a cure for the infection. This is why they demanded eight million humans be handed over - they need to extract the cure from human blood to save their own species.

Unlike other humans who require massive blood extraction to produce a cure, Heather possesses a unique blood composition. A small portion of her blood is sufficient to cure a single Kulku, making her extraordinarily valuable to the alien species. This special trait becomes central to Jal's plan to use her as a trophy.

Jal plans to use the Raeg weapon to destroy Earth after taking Heather to Kulku space. His motive is to return to his homeworld as a celebrated hero who secured the cure and eliminated the enemy planet. By framing the destruction as a military victory, he positions himself as a savior who brought back the valuable human specimen.

The Raeg is a devastating Kulku weapon capable of destroying entire planets. It represents the ultimate threat to Earth throughout the film. The resistance develops a countermeasure using a modified weapon mounted on a telescope at a remote observatory, which they attempt to use to destroy the Raeg before it can be unleashed.

Dr. Stephen Chase joins the resistance after his daughter Heather is selected in the lottery to be handed over to the Kulku. Driven by both family love and his scientific expertise, he dedicates himself to designing weapons for the resistance and finding ways to stop the Kulku's harvesting operation while rescuing his daughter.

Kor is a Kulku who shows sympathy for humanity and questions his species' brutal methods. Despite being Kulku, he refuses to betray his own people even when he disagrees with their actions. His conflicted loyalty creates internal tension throughout the film as he walks between both sides.

After Kor is mortally wounded by Jal, he attempts to detonate the Raeg weapon as a final act to save his dying species from extinction. Heather kills him to prevent him from triggering the weapon and destroying Earth. This act represents her transition from victim to survivor defending her planet.

As the Kulku harvesting operations expand and threaten more civilian populations, Major General Skyler shifts from viewing the resistance as enemies to recognizing them as necessary allies. The U.S. Army joins forces with the resistance to combine military resources with Chase's weapon designs for a stronger counterattack against the alien invaders.

The Kulku demand eight million humans as a specific quota needed to extract enough biological material to create a cure for the virus killing their species. This number represents the minimum they calculate is necessary to save their civilization, making it a non-negotiable demand that forces global governments to choose between compliance or total war.

The ending is bittersweet because while Earth is saved from destruction and the main characters survive, nearly eight million humans have already died during the Kulku invasion. Additionally, the Kulku are left to face extinction on their virus-ridden homeworld without the human cure, leaving no true winners - only survivors bearing the scars of war.

When the Kulku demand eight million humans, the United States chooses a nationwide lottery to select which citizens will be handed over. This desperate measure represents an attempt at perceived fairness - randomly selecting individuals rather than targeting specific groups - though it ultimately forces ordinary citizens into an impossible situation.
