Alien Siege

The Kulku threaten to harvest eight million humans to cure their virus. To meet the demand, nations release prisoners while the United States holds a lottery to pick eight million people, including Heather.

Heather is announced as one of the eight million chosen for the lottery. Dr. Stephen Chase tries to intervene as the crisis escalates.

Dr. Chase joins the human resistance to fight the Kulku. He also designs a weapon that could potentially turn the tide of the war.

The resistance makes some progress with Chase's weapon, but Heather is captured by the Kulku. She is taken aboard the Kulku mothership in orbit for the cure test.

Jal, the Kulku ambassador, plans to send Heather to Kulku to complete the exchange. He also intends to destroy Earth with the Raeg weapon to ensure her travel remains possible.

Major General Skylar's U.S. Army forces join the resistance and bring critical firepower. Together they coordinate operations to stop the Kulku and protect Heather.

The resistance repurposes a telescope from an observatory into a modified weapon based on Chase's design. They plan to fire on the Raeg to prevent Earth’s destruction.

A traitor reveals the resistance plans to Kor, a Kulku who is sympathetic to humanity but refuses to sacrifice his own race. Kor is reluctant to abandon his people and seeks a solution that preserves both sides.

Kor lands a strike team at the observatory to halt the resistance's preparations. The confrontation raises the stakes as humans and Kulku clash.

Chase boards Kor's ship and forces him to fly toward the Kulku mothership to rescue Heather. This daring move sets up the next rescue and confrontation.

Chase frees Heather, and Jal fights back, slaughtering some Kulku. Heather's distraction gives Chase the opening to kill Jal.

In the climactic moment, Kor is dying but attempts to detonate the Raeg to save his own race. Heather confronts him and finishes him off in revenge for Earth’s suffering.

At the observatory, Blair and Skylar's forces neutralize the remaining Kulku threats. The weapon is fired, destroying the Raeg at the last moment.

Chase pilots a Kulku shuttle back to the observatory and reunites with Blair and Skylar. Heather joins them as the situation stabilizes and they await the aftermath.

A news broadcast reveals that nearly eight million people died during the invasion. The world begins to recover as the Kulku presumably die out on their homeworld.
