Osiris

During a nighttime operation in a remote desert, Kelly's team is ambushed by an unseen force. In the chaos, the soldiers are mysteriously abducted and vanish from the battlefield.

The soldiers awaken, disoriented and confined inside translucent stasis pods aboard a massive, dimly lit alien spacecraft. They realize they are no longer on Earth and are trapped in alien containment.

The stasis pods dissolve, expelling the soldiers into the ship's dim corridors. They quickly discover skinned human corpses and unfamiliar weapons and technology around them.

The team is attacked by tall, eyeless aliens with armored skin and energy shields. They fight their way through the corridors using their remaining weapons and scavenged gear.

They encounter Ravi, a young Russian woman, who explains that the ship harvests humans for food. She agrees to help and leads them through lesser-traveled maintenance tunnels.

Ravi reveals a hidden safe room and leads the team toward it. The group travels through maintenance tunnels, wary but hopeful about finding safety.

Following the route, they drop down a vent into a pool of blood and human remains. Anya, a fellow survivor, appears and helps rescue them.

Anya explains she has survived on the ship for twenty to thirty years and has a plan to destroy the alien communication array with explosives. To execute it, a distraction is needed, so Kelly agrees to draw as many aliens away as possible.

The distraction initially works, but Scars detects motion on a sensor, allowing the aliens to track them. The group faces intensified pursuit as a result.

The group is reduced to Kelly, Ravi, Nash, and Anya. Anya detonates explosives to destroy most of the pursuing aliens in a final, selfless stand.

The survivors reach a hatch leading outside, but Nash is killed by Scars in the pursuit. The loss leaves Kelly and Ravi to continue alone.

Kelly lures Scars into an open hatch and closes it, severing the alien's fate by cutting him in half. With Scars defeated, the path to escape widens.

Kelly and Ravi reach an exterior vantage and look up at an orange glow in the distance. They behold the destroyed city of Paris, a stark symbol of what remains of the world and what lies ahead.
